THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -These cells develop into sperm or ova. The ova mature in the ovaries of females, and the sperm develop in the testes of males. Each sperm cell, or spermatozoon, is small and motile. The spermatozoon has a flagellum, which is a tail-shaped structure that allows the cell to propel and move.

Detailed explanation-2: -The testes are the site of gamete production in males. The male gamete is called sperm. It is produced in the seminiferous tubules and testosterone is produced in the interstitial cells. Sperm are motile (able to swim) however they need a fluid to swim in.

Detailed explanation-3: -Male gametes are contained within pollen grains, which are released from the anthers at anthesis.

Detailed explanation-4: -Sperm is the male gamete produced by the testis. Ovum is the female gamete and it is produced by the ovary. Fusion of sperm and ovum results in the formation of zygote.
