Detailed explanation-1: -They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm.

Detailed explanation-2: -In the human reproductive process, two kinds of sex cells, or gametes (GAH-meetz), are involved. The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female’s reproductive system. When sperm fertilizes (meets) an egg, this fertilized egg is called a zygote (ZYE-goat).

Detailed explanation-3: -A gamete is a reproductive cell of an animal or plant. In animals, female gametes are called ova or egg cells, and male gametes are called sperm. Ova and sperm are haploid cells, with each cell carrying only one copy of each chromosome. During fertilization, a sperm and ovum unite to form a new diploid organism.

Detailed explanation-4: -The female gametophyte is also commonly called the embryo sac or megagametophyte. The male gametophyte, also called the pollen grain or microgametophyte, develops within the anther and consists of two sperm cells encased within a vegetative cell (Gifford and Foster, 1989).

Detailed explanation-5: -How are eggs produced? Eggs are produced in the ovaries, which are normally situated towards the back of a woman’s abdomen below the kidneys. The eggs develop from tiny cells inside the ovaries, going through various stages of development – known as oogenesis – until they are released once a month during ovulation.
