diversity and adaptations of organisms

Adaptation - Adaptations are favourable, heritable variations or changes that enable an organism to increase its chances of survival. Such variations are the result of genetic recombinations or mutations. Adaptations can be either permanent (i.e., heritable f..

The leaves are reduced to small scaly structures (Casuarinas) or spines (Opuntia) The leaves are shed when water is scarce Water storage structures develop in the leaves They have a thick cuticle and a multiple layered epidermis They have sunken stomata They have long roots, which ..

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..

Animal Diversity - 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..

Habitat and Adaptations - Habitat is the term given to the special environment in which an organism lives and grows. In order to survive, plants and animals develop special features called adaptive characters that help them to adjust to a particular habitat. This is kn..

The phenotype is the physical expression of the organism. The phenotype shows variations due to differences in the environmental conditions in a habita..
