diversity organisms summary

Introduction - Every organism whether plant or animal is unique in itself. There is a wide diversity in the flora (plants) and fauna (animals) in the world. The diversity we see today is the result of 3.5 billion years of organic evolution. During the course ..

Taxonomy is a regular branch of science that is involved with the purpose of arranging or grouping organisms..

Question 1 - Question: What is the necessity of classification of organisms? Answer: Organic evolution has been taking place for 3.5 billion years. It is impossible to study every living organism from an individual level. Therefore, classification is necessary to facil..

Among the members of the animal kingdom, about 95% do not posses a backbone (or vertebral column) and hence are described as invertebrates. The remaining animals represent a group called chordates, which posses a solid supporting structure on the dorsal side of the body called notochord, at some st..

Biology is a branch of science that deals with the study of life. Hence, it is also called life science. The simple curiosity of human beings to observe nature and the human basic instincts for survival and gathering food probably had a role in the birth and development of biology. Biology ..

In the modern system of classification, living organisms are grouped under five kingdoms, as proposed by Whittaker (1966). The Kingdom Monera includes bacteria and blue green algae, both of which possess prokaryotic cells. Bacteria are unicellular prokaryotes that have a wide dist..

The numerical strength and biomass of organisms affect the functioning of ecosystem. In ecosystems, the biotic communities usually contain a few common species represented by a large number of individuals or by a large biomass and a comparatively large number of individual species occurr..

Summary - Organic evolution refers to the slow and gradual process by which living organisms have changed from the simplest unicellular form to the most complex multi-cellular forms that are existing today. Organic evolution primarily involves modifications i..

Summary - The cells of all living organisms consist of protoplasm, which is bound by a cell membrane. Prokaryotic cells and cells of algae, fungi and higher plants contain a cell wall outside the cell membrane. Some protozoans cells show the presence of a cell coat outside the c..
