Explanation:

Question 19

Meiosis is the process of cell division that produces gametes (sex cells) with half the number of chromosomes. Germ cells (germline cells) in the reproductive organs undergo meiosis. In males, these are spermatogonia located in the testes, and in females, these are oogonia located in the ovaries.

Somatic cells are all the cells in the body except for the germ cells. They make up tissues, organs, and organ systems and undergo mitosis for growth, repair, and maintenance. Examples include skin cells, muscle cells, liver cells, etc., located throughout the body in various tissues and organs.

Fertilization is the biological process where a sperm cell (male gamete) fuses with an egg cell (female gamete) to form a zygote. This zygote then has the full set of chromosomes (diploid) and will develop into a new organism.

Answer:

The cells in our bodies that undergo meiosis are germ cells (germline cells). In males, they are located in the testes (spermatogonia that develop into sperm), and in females, they are located in the ovaries (oogonia that develop into eggs).
