VARIATION
1. Variations make some individuals better fitted in the struggle for existence.
2. They help the individuals to adapt themselves according to the changing environment.

5. They constitute the raw material for evolution.
6. Variations give each organism a distinct
Reproduction
1.Continuity of species
2.Population organisation
Basic features of reproduction:
1.Synthesis of RNA, proteins and other bio-chemicals
2.Replication of DNA
3.Cell division
4.Growth of cells
5.Formation of reproductive units
6.Formation of new individuals from reproductive units
