Reproductive cell
Reproductive cell
A reproductive cell or sex cell is a type of cell that is involved in the reproduction of an organism. These cells, also known as gametes, are produced by the gonads (the ovaries and testes). In humans and other mammals, the male gametes are called sperm and the female gametes are called ova or eggs.
Types of reproductive cells[edit | edit source]
There are two main types of reproductive cells: haploid and diploid. Haploid cells, such as sperm and ova, contain only one set of chromosomes, while diploid cells, such as the cells of the body (somatic cells), contain two sets of chromosomes.
Sperm[edit | edit source]
Sperm are the male reproductive cells. They are produced in the testes and are responsible for fertilizing the female's egg during sexual reproduction. Sperm are small and motile, allowing them to travel to the egg.
Ova[edit | edit source]
Ova, or eggs, are the female reproductive cells. They are produced in the ovaries and are released during the menstrual cycle. Ova are larger than sperm and are not motile.
Reproduction[edit | edit source]
During sexual reproduction, a sperm and an egg combine in a process known as fertilization to create a new organism. The resulting cell, called a zygote, is diploid, meaning it contains two sets of chromosomes - one from each parent.
