Here's a breakdown:

* Gametes: Reproductive cells (sperm and egg) that carry half the genetic material of an organism.

* Somatic cells: All the other cells in the body that are not involved in reproduction. These include muscle cells, nerve cells, skin cells, and many others.

Somatic cells are diploid, meaning they have two sets of chromosomes. They are formed through mitosis, a process of cell division that creates two identical daughter cells.
