NEET BIOLOGY

Detailed explanation-1: -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-2: -A developing egg is called an oocyte. Its differentiation into a mature egg (or ovum) involves a series of changes whose timing is geared to the steps of meiosis in which the germ cells go through their two final, highly specialized divisions.

Detailed explanation-3: -An egg cell or ovum is a female reproductive cell that fuses with sperm in the process of fertilisation. This ovum develops into its mature form via a process called oogenesis. In viviparous animals, this ovum is fertilised inside the body of the females. Whereas, the embryo development takes place in the uterus.

Detailed explanation-4: -Answer and Explanation: The female gametes (sex cells) are called eggs (ovum). Females are born with all of the eggs their bodies will produce, and they are stored in the ovaries.

Detailed explanation-5: -The ovum itself has a central nucleus that contains the female’s genetic material; this, with the genetic material in the sperm cell, determines the inherited characteristics of the child. Surrounding the nucleus is a cell plasma, or yolk, that contains nutritional elements essential to the developing egg cell.
