Question 21
Reproduction is essential to living organisms in order to

(a) keep the individual organism alive
(b) fulfil their energy requirement
(c) maintain growth
(d) maintain the continuity of species from one generation to another generation

Q. Assertion :Algae and fungi switch to asexual method of reproduction before the onset of adverse conditions. Reason: Asexual reproduction may introduce variations and leads to the formation of many clones.

Q. Assertion :As favourable variations are transmitted from generation to generation, successive generations become better adapted to the environment, more over, new adaptations may arise due to changing environment. In this way, the adaptive traits preserved by natural selection, will gradually change the characteristics of a species. Reason: This explains the origin of species.
