Detailed explanation-1: -In animals, egg cells are also known as ova (singular ovum, from the Latin word ovum meaning ‘egg’). The term ovule in animals is used for the young ovum of an animal. In vertebrates, ova are produced by female gonads (sex glands) called ovaries. A number of ova are present at birth in mammals and mature via oogenesis.

Detailed explanation-2: -Egg cells are the female sex cells-also known as gametes. It’s the job of the female egg cell to connect with the male sperm cell in order to become fertilised and produce offspring. In the illustration below you can see how the sperm must become connected with the egg cell in order to fertilise it.

Detailed explanation-3: -The eggs of most animals are giant single cells, containing stockpiles of all the materials needed for initial development of the embryo through to the stage at which the new individual can begin feeding. Before the feeding stage, the giant cell cleaves into many smaller cells, but no net growth occurs.

Detailed explanation-4: -Ovaries are the site of egg development. Egg development occurs in structures called follicles, which are lined with specialized cells called follicular cells that surround the egg and promote egg development.

Detailed explanation-5: -Gametes are an organism’s reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome.
