Name the transport structures of a flowering plant xylem vessels and tracheids transport water and mineral salts from the soil (iii) The formation of soils through rock weath­ering and soil-organisms continues and the thickness of soils continues to increase with time. Geography. On an average, there are four vertical strata of plant community in a given region mainly in the deciduous forests of the temperate regions: (i) Dominant layer represents the topmost layer of the plant community (fig. I highly recommend you buy both the Notes as the topics covered in one notes are not included in the other. An ecosystem succession is the changing phases of dominant plant species occupying a particular climatic habitat or ecosystem. H. L. Mason (1946) discusses very helpfully three aspects of problems involving the distribution of plants. Meaning of Plant Community 2. The most important topics in the science and technology sections are – Human Body, Plant System, and Basic Physics Modules.

Plant Diversity (formerly Plant Diversity and Resources) is an international plant science journal that publishes substantial original research and review papers that . Class VII - Geography Chapter 1 - Environment Other Chapters Environment. Clements (1916) biotic suc­cession of vegetation community is primarily of two types e.g., primary biotic succession and secondary biotic succession: Primary succession refers to developmental se­quence of vegetation in those bare areas where there were no vegetation and animals earlier. Free pure Physics, Chemistry, Geography and Social Studies revision notes. The soil zones are colonized by various micro­organisms which decompose the organic matter and help in the process of energy transfer. Water. The study of the distribution of plants is the science of plant geography. There is great variation in plant species from one region to another region but few plants are common to all sub- kingdoms and regions. When the vegetation community of any region is disturbed before reaching its climax sere by human interferences (through slow but long-term activities like deforestation or burning of vegetation etc. ‘A group of populations of different species living in the same local areas and interacting with one another is called ecologi­cal community’. (iv) Fourth layer represents mosses on the ground surface and is also called as moss layer or ground layer. Diffusion and osmosis; 3. Aspirants should read geography from NCERT Books for UPSC to prepare for the IAS Exam. A secondary layer very often called as co- dominant layer is formed just below the crown or dominant layer by those large trees which are rela­tively shorter than the largest trees (fig. Copyright 9. Geography A Level Notes garikaib 2019-04-10T06:56:51+02:00. 43.1). Basic Structure of Plants The three basic parts of most vascular plants are the leaf, the stem, and the roots. For example, two habitats may have similar floras but their vegetation may vary from one another and two habitats having different floras may have similar vegetation. Distribution of Plants: 6 Kingdoms | Biosphere | Geography. Plant Nutrition; 5. The group or association of plants growing together in a particular habitat is called plant commu­nity. (iv) Secondary community of mosses replaces the pioneer community of algae and lichens in due course of time. Prohibited Content 3. It is about how, why, and where human and natural activities occur and how these activities are interconnected. In this article we will discuss about:- 1. Eucalyp­tus is said to be related to mimosa which is still found in South America (only a few species). These plants represent most plants of the gradient such as garden flowering plants (e.g., Loplia, Kniphogia, Erica Freesia etc.). This vertical layering pattern or vertical stratification of plants is the result of competition among various species of plant community to get sunlight because it is the primary source of energy for photosythesis through which these plants manufacture their food. Account Disable 11. Africa, the second-largest continent, is bounded by the Mediterranean Sea, the Red Sea, the Indian Ocean, and the Atlantic Ocean.It is divided in half almost equally by the Equator. This uppermost stratum is also called crown or canopy which repre­sents the highest limit of plant community in a given region. The vertical stratification of plant community is well developed. In high latitudes, it is simply too cold for the atmosphere to hold enough water vapor to produce high rates of evapotranspiration and there are fewer plants present. These are very wide and must be understood from the core rather than just skimming the concept from above. vegetation succession. The development of different species of plant community of a given region takes place through the processes of adaptation, competition and natural selection. There is a zonal pattern of vegetation from equator towards the poles and from seal level to vegetation level on the high mountains. Freshwater accounts for only 2.7% and 70% of these occurs as ice-sheets and glaciers in Antarctica, Greenland and mountain region and they are inaccessible because of their location. Gradually and gradually seasonal and perennial grasses are developed along with new groups of animals like nematodes, spring- tails etc. ); (iii) Biotic factors (effects of living organisms mainly animals and man of a particular habitat on plants, interactions between different plant species and between plants and animals like natural selection, com­petition, mutualism, paraticism etc. Later on the spreading of Atlan­tic sea-floor, disruption of Gondwanaland and west­ward drift of South America from Africa became responsible for the origin and development of new species at regional level and therefore variations in the plant species of South America and Africa were intro­duced. Content Guidelines 2. There may be two alternative routes of competition among the plants e.g. (GS Paper- 1 Indian Heritage and Culture, History and Geography of the World and Society) Earth is splendid terrestrial haven. : (i) Climatic factors (sunlight, temperature, moisture and humidity, pre­cipitation, soil-moisture etc. The social group­ings of plant species are called plant community of which plant is the fundamental basic unit. Content Guidelines 2. (vii) The final stage or ‘sere’ of the successional development of vegetation community is character­ized by the development of giant and very tall trees; the density of which increases rapidly and the whole of the concerned habitat is covered with dense and tall trees. 43.1) which is determined by the canopy of the largest trees. At this stage a very significant development takes place in that the seeds of flowering plants (phanerogams) are brought from the neighbouring areas to the concerned habitat by winds and given birth to trees in the otherwise shrub-dominated habitat. Canopy. Different species of plants are evolved in a habitat having favourable environmental conditions wherein different species of plant community grow together having different life-forms. The plants of this kingdom belong to the category of cryptophytes which bear buds in the form of bulbs and tubers which are buried in the soils. An example of secondary succession may be given from the hill areas of north-east India where jhuming or shifting cultivation is a common practice. Plant Nutrition Revision Notes: 4. The mosses spread over the soils like thin sheets and thus soils are covered by the mosses. This region includes the whole of South America except southern Chile and Patagonia. It may be remembered that the native vegetation of this region before the European colonization consisted of temperate evergreen forests which were extensively cleared off by the Europeans for agricultural proposes and thus the sclerophyllous shrubs developed in this region at later date as secondary succession of vegeta­tion. Form 5. ), the resultant vegetation is called sub-climax vegetation. Our Changing Earth. Geography Geo—earth Graphy—picture or writing Geography has many subdivisions (Fig.1.2) The open community is now changed to closed community (which means that no part of the concerned habitat remains without vegetation, in other words, whole area of the habitat is covered with vegetation). Such areas or sites may be newly emerged sea floor, cooled and solidified basaltic surfaces due to recent lava flows, exposed lake bed due to drying of water, newly formed sand dunes, flood plains formed by recent alluvia, heaps of debris accumulated by man, the areas of exposed rocks due to melting of ice from the glacial areas, etc. Horizon ‘B’ - Lies below top soil. 1. However, it is saline and not useful for human consumption. Africas physical geography, environment and resources, and human geography can be considered separately. This final phase or ‘sere’ of the successional develop­ment of vegetation community is called climax commu­nity, climax succession, climatic climax vegetation etc. The sequence of the development of vegetation community (biotic suc­cession) is called sere. Principles of organization. As 95% of the users buy both, it is not logical for me to add the same content in both the notes as it would increase the number of pages and the printing cost. The untouched areas still have sclerophyllous shrubs which attain the height of a few meters. Genera and family of plants and major vegetation of the aforesaid floral kingdoms and floral provinces or regions. Cell Structure and Organisation Revision Notes: 13. This phase (sere) of community development is domi­nated by herbaceous plants and thus by herb commu­nity. A few genera are common to this kingdom and palaeotropical kingdom mainly Africa because the original flowering plants were developed in South America and Africa during Cretaceous period when all members of Gondwanaland were united together. Thus, new vegetation develops under new changed environmental conditions in place of plagioclimax vegetation and the successional develop­ment of vegetation community takes place under nor­mal sere. The typical endemic floras of Australia having unique characteris­tics have developed due to its isolation from other continents of the southern hemisphere because of con­tinental drift. Introducing Geography: Geography is the study of the evolving character and organization of the Earth’s surface. The abandoned area or the old clearance is again colonized by vegeta­tion through various stages and it attains climax veg­etation or climax succession in a short period of time (a few years), because the sequence of secondary succes­sion is more rapid than the primary succession due to availability of mature soils. Copyright 9. The floral kingdom has developed in the south­ern tip of Africa wherein the plants having bulbs and tubers have developed and these represent the typical plant species of this floral kingdom. The scheme represents a compromise between political and botanical divisions. Given World History handwritten notes are very important for UPSC, SSC, TET, State level PSC which represents mature ecosystem. (ii) Dust particles blown by wind settle down in the concerned habitat. NOTES 1. a) i) Define transport . or. Photosynthesis is a chemical reaction that takes place inside a plant, producing food for the plant to survive. - Where most plant roots are found. Enzymes; 4. Before uploading and sharing your knowledge on this site, please read the following pages: 1. - Has small spaces between particles and hence less aerated. This is also called as shrub layer. In one of the most stimulating phytogeographic essays of recent years. are evolved. The soil zone, though very thin in the beginning, is colonized by micro-organisms. Beautiful, ice-clad Mount Baker, elevation 10,778 feet (3285 m), is a Cascadian volcano 1/2 million years in the making. The gradual develop­ment of grasses covers the whole area of the concerned habitat and thus is developed a dense vegetation cover which changes and modifies the micro-climates of the concerned habitat. The most outstanding and typical species of the grasses were Tussock Grasses though a few spe­cies of Sedges (plants which grow in water) and dicoty­ledon shrubs were also developed but these original native vegetation have undergone massive modifica­tion and transformation since the colonization of New Zealand by the Europeans. The dispersal of these garden plants became possible when South Africa was colonized by Europe­ans who distributed these garden flowering plants from South Africa to the gardens of other parts of the world. Terms of Service 7. (ii) Second layer is located below the dominant or crown layer and is represented by plants of shrubby life-form. Such deflected climax is called plagioclimax and its various stages are called plagio sere.

The different species of this unique genera of eucalyptus are so dominant in Aus­tralia that they represent 75 percent of all Australian plants. advance our understanding of the past and current distribution of plants, contribute to the development of more phylogenetically accurate taxonomic classifications, This final plant community is referred to as the . This phase of development of vegetation com­munity is characterized by maximum growth and de­velopment of plants. Disclaimer 8. The land plant species of the world are grouped into 6 major floristic kingdoms on the basis of their worldwide distribution (fig. Plagiarism Prevention 5. Download CBSE Class 9 Social Science Geography Natural Vegetation And Wildlife Notes in pdf, Geography chapter notes, class notes mind maps formulas Revision Notes CBSE Class 9 Geography Concepts Natural Vegetation and Wildlife. (vi) With the march of time there is developed large shrubs in the concerned habitat and the herb community is dominated and replaced by scrub com­munity. When the disturbances in the successional develop­ment of vegetation continue for long time, stages of normal sere of the development of vegetation do not take place but these ‘sere’ are deflected by those factors which bring in disturbances in the successional development of vegetation. Content Filtration 6. It may be pointed out that such disturbed ecosystems or habitats still contain mature soils and some original vegetation and therefore the initial stage or sere of secondary succession of plant community is quite different from the initial stage or ‘sere’ of primary succession which starts on a bare rocky surface, having no earlier plants and animals. The replacement of one vegetation community in a given habitat by the other vegetation community is called biotic succession. Report a Violation 10. Before uploading and sharing your knowledge on this site, please read the following pages: 1. Thus, the principle of survival of the fittest becomes effective in the community develop­ment of plants. The dense vegetation cover de­creases ground temperature and sunlight at the ground surface but increases moisture content of the soils because evaporation of moisture from the soil surface is effectively decreased due to shade provided by dense vegetation cover. New dense matting of mosses also provides organic matter to the soils and thus the soils are enriched by the addition of organic nutrients. Class 11 Geography Notes Chapter 15 Life on the Earth Life on the earth is found almost everywhere. ... Biodiversity (plant and animal diversity) Plant and animal adaptation; Form 6. Secondary succession refers to the develop­mental sequences of vegetation in those areas which had vegetation cover earlier but now have been ren­dered nude or bare due to destruction of vegetation (either partly or completely) either by natural proc­esses (like lava flow, prolonged drought, glaciation, natural widespread forest fires through lightning, se­vere storms, catastrophic floods etc.) Air. Plant adaptations in tropical forests. Account Disable 11. - Contains most of plant nutrients. Under this cultivation, first forest is cleared from small areas through burning and then the soil is cultivated for agricultural crops for a few years. The starting point was the "need for an agreed system of geographical units at approximately 'country' level and upwards for use in recording plant distributions". Disclaimer 8. On the basis of importance and dominant role of plants in the biosphere the study of plants is given more significance. Diffusion and Osmosis Revision Notes: 2. Terms of Service 7. Thus, the vegetation community upto this stage (sere) is mixed with lichens, mosses, grasses, shrubs and trees. When the soil loses its fertility, that area is left out and new areas are cleared of vegetation for cultivation. Biosphere, Distribution of Plants, Geography, Plants. Resources for top A1 candidates taking the 2021 Singapore-Cambridge GCE O Level exam. Geography is an interesting subject which covers land (lithosphere), water (hydrosphere) and air (atmosphere). There are over 600 species of eucalyptus which greatly vary as regards their general characteristics as they range from tall, giant and shady eucalyptus trees to dwarf and stunted desert eucalyptus trees. Warm Up - Take a Warm Up test with just 10 questions to check your retention. This kingdom includes most of Africa, South West Asia, South Asia, South East Asia and southern and middle portions of China. Leaf - The leaf is an organ of a plant that is specialized for photosynthesis. NOTES ON THE "HISTORICAL FACTOR" IN PLANT GEOGRAPHY By Robert E. Woodson, Jr. Where evapotranspiration is high and so is plant growth. In other words, ‘those plants which grow together in a particular habitat are referred to as a plant commu­nity, by which something more than a mere collection or assemblage is implied’. One can see extensive plantation of eucalyptus in India particularly along the rail and road sides and it is being expanded rapidly by deliberate actions of man in all parts of the country irrespective of environmental requirements and suitability of this unique exotic plant. Carbon dioxide, water and light are all needed for photosynthesis to take place. This is called forest commu­nity and the sere of this successional development of vegetation community is called preclimax. (iv) On the basis of characteris­tic features of plant communities etc. Physical Geography Notes: Introduction Unlike most scientists in related disciplines, Geographers may focus their research on nearly any topic or subject related to the scientific analysis of human or natural processes on earth. Topics of Geography and Environment have a lot of convergence. ); (v) Tectonic factors (continental displacement and drift, plate movements, endogenetic forces and movements, vulcanicity and seismic events etc. Plagiarism Prevention 5. Oceans covers about 2/3rds of the earth’s surface and supports a rich variety of plant and animal life. The vegetation developed during the deflected sere persists so long as the factors responsible for the disturbance remain active. About 100 million years ago temperate grasses devel­oped as the native vegetation of this region (New Zealand). The sub-tropical forests of New Zealand are of evergreen type which is characterized by dense cover of tall trees having different vertical strata of other plants. The best app for CBSE students now provides Land, Soil, Water, Natural Vegetation and Wildlife Resources class 8 Notes Geography latest chapter wise notes for quick preparation of CBSE exams and school based annual examinations. Prohibited Content 3. Enzymes Revision Notes: 3. 43.2) as given below: This floristic kingdom includes the plants of whole Australia which is characterized by typical plant species e.g., eucalyptus. This floral kingdom includes the whole of North America except Middle America, Greenland, entire Europe, northern Asia and Arctic region. Taking notes is an efficient way to organise the study material for revision. For instance, if there are two simi­lar habitats wherein both have grasses and sal trees but there is overwhelming dominance of grasses and sparse distribution of sal trees in the first habitat whereas the second habitat is characterized by dense sal trees and sparse distribution of grasses, the vegetation of the first habitat will be grasses whereas the vegetation of the second habitat will be sal forest. The distribution of plants is affected and controlled by a variety of factors e.g. Natural Vegetation and Wildlife ... Now, you have read the notes on this chapter, take a test to check your understanding of this chapter. Rocky Mountainous Region (RMR); Atlantic – North American Region (ANAR, fig. These bulbs and tubers give birth to other plants as new shoots come out from these bulbs and tubers and are developed as plants. Thus, primary succession of vegetation on a bare rock surface having no prior vegetation and animals starts and is completed through the following stages: (i) The initial plant-free site has relatively dry environment. Such competition is called intraspecific competition which means survival of the strongest plants and elimination of weaker plants but the preser­vation of species is maintained. Thus, solar energy converted into the food or chemical energy is transferred to differ­ent animals and micro-organisms through different trophic levels of food chain. Plants directly receive and trap solar energy (light energy) and prepare their own food with the help of sunlight through the process of photosynthesis. This is possible only when the environ­ment of the concerned habitat is wet but if the environ­ment of the concerned habitat is dry and the surface is of sandy desert, much area is still open and devoid of vegetation. Tree trunks – The trunks of the trees are tall so that they can reach sunlight. climax vegetation. The association or group of plant communities of any region is called vegetation. The concepts should be clear which will help ); (iv) Physical fac­tors (reliefs and topography, slope angle, gradient and slope aspect, etc. The pioneer plants are established upon the bare rocks of the initial plant-free site. Characteristics Plant Community 3. Download World History Handwritten Notes PDF by Anudeep Shetty. There is undergrowth of herbaceous shrubs in the sclerophyllous shrubs. This floral kingdom is further divided into 3 sub-kingdoms e.g. The main species of the coniferous family of gymnosperms are Podcarpaceae, Cupressaceae and Araucariaceae whereas flowering plants are included in Angiosperms of which Nothofagus is the most important plant. - Contains active micro organisms which breakdown organic matter into humus. There is a wide range of variations in the distri­bution of vegetation on the globe. Content Filtration 6. Learn about and revise ecosystems on a national and worldwide scale with GCSE Bitesize Geography (AQA). Living organisms are found from the poles to the equator, from the bottom of the sea to several km in the air, from freezing waters to dry valleys, from under the sea to … Introducing Physical Geography _____ I. There is a wide range of variations in the distri­bution of vegetation on the globe. Eucalyptus has been dispersed and distributed by man (deliberately) from Australia to almost every continent. The canopy of these scattered trees is much higher than the stratum of shrubs. Plant adapt to the extreme humid conditions in the tropical rainforest. (ii) Tall Tussock Grasslands have the main species of Chiomechloa. Therefore, areas like the tropics that are warm and moist foster plant transpiration allowing more plants to grow there. In other words, the transitional stages of sequential changes from one vegetation com­munity to another vegetation community are called SERE which is complete when the succession of veg­etation community after passing through different phases of changes culminates into equilibrium or mature con­dition. 43.2); Arctic and Sub-Arctic Region (ASAR); Europe-Siberian Region (ESR); Mediterranean Re­gion (MR) etc. : (a) If the plants of the concerned habitat are of the same species, there is competition for the aforesaid elements among the different members of the same species and only the fittest plants survive during the competition.
