What role do gametes play? What distinguishes them from somatic cells?

Gametes are germ cells involved in sexual reproduction. Gametes contain a half haploid set of chromosomes; in somatic cells, the complete set of chromosomes is double.
What changes occur in the cell before division? Before division, an interphase stage proceeds. Interphase (from Lat. Inter – between from Greek. Phasis – appearance) is a part of the cell cycles between two divisions. In cells that have lost the ability to divide, the interphase is considered to be the period of the last division until their death. During the interphase period, the cell functions actively; metabolic processes are intensively taking place in it, including preparation for division
