MEDICAL PHYSIOLOGY

Detailed explanation-1: -Spermatozoa (sperm) are the male sex cells that carry a man’s genetic material. They are so tiny that they can’t be seen without a microscope. In a healthy man, one ejaculation usually contains between 40 million and 600 million sperm.

Detailed explanation-2: -Male gametes in humans is called sperms. Sperms are produced by testes. Sperms fuse with egg produced by ovaries to form a zygote.

Detailed explanation-3: -Sperm cells or spermatozoa are small and motile due to the flagellum, a tail-shaped structure that allows the cell to propel and move. In contrast, each egg cell or ovum is relatively large and non-motile. In short a gamete is an egg cell (female gamete) or a sperm (male gamete).

Detailed explanation-4: -A pollen grain contains two male gametes. One of the male gametes fuses with female gamete to frame zygote and the other one breakers with the polar cores to shape the essential endosperm core.
