Answer:*Sex Cells*Sex cells, also known as gametes, are the reproductive cells produced by males and females that are involved in sexual reproduction. These cells are crucial for the creation of a new individual.*Types of Sex Cells*1. *Sperm cells (Spermatozoa)*: These are the male sex cells produced in the male reproductive system.2. *Egg cells (Ova)*: These are the female sex cells produced in the female reproductive system.*Production of Sex Cells*1. *Male Sex Cells (Sperm)*: Sperm cells are produced in the *testes*, specifically in the seminiferous tubules of the testes, through a process called spermatogenesis.2. *Female Sex Cells (Eggs)*: Egg cells are produced in the *ovaries*, specifically in the ovarian follicles, through a process called oogenesis.*Importance of Sex Cells*Sex cells are essential for sexual reproduction, as they carry genetic material from each parent to form a new individual. When a sperm cell fertilizes an egg cell, it results in the formation of a zygote, which develops into a new organism.
