This chapter defines cell devision, Basis of Heredity (Chromosome, DNA, and genes in Plant and Animal Cell)

*CELLs are continuously are dying and replaced by new Cells.

The cell that divides is called Parent cell, resulting in producing new cells called daughter cell.

Mitosis:In which body cells divide for growth, repairing and development.

Meiosis takes place when sex cells are divided and gametes are formed during the process of reproduction in humans, others.

DNA: It saves genetic information.
