Choose all that are gamete cells.
A
egg cell
B
blood cell
C
sperm cell
D
neuron
Explanation: 

Detailed explanation-1: -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-2: -in males, these four cells are all sperm cells. in females, one of the cells is an egg cell while the other three are polar bodies (small cells that do not develop into eggs).

Detailed explanation-3: -Gametes are formed through meiosis (reduction division), in which a germ cell undergoes two fissions, resulting in the production of four gametes.

Detailed explanation-4: -Gamete refers to a haploid sex cell that is a sperm in males and egg (oocyte) in females. Zygote is the diploid cell that results from the fertilization between an egg and a sperm. In mammals, the sperm (male gamete) fertilizes the egg (ovum, the female gamete) and the fertilized egg is called a zygote.
