Definitions of Somatic Cell and Gamete

Somatic cell: The cells of the multi-cellular organisms that only form the physical structure but do not take part in reproduction are said to be somatic cells.


(i) Chromosomal numbers of these cells are usually diploid

(ii) In order to form new somatic cells, they undergo mitosis division.

Reproductive cell or gamete: The types of cells that only take part in reproductive activities arc known as reproducing cells or gametes.


(i) The chromosomal numbers of these cells are always haploid (n).

(ii) These cells are formed by meiotic- division of reproductive mother cells.

(iii) Reproductive cells arc of two types, such as- a) Sperm (n) and b) Ovum(n)
