Body cells are those that are responsible for the formation of tissues and organs, while a gamete is that cell responsible for reproduction.
- Gametes are sex cells, when a male gamete joins a female gamete in the framework of sexual reproduction of plants and animals, a zygote is formed.
- Body cells are any cell in the body that are not gametes, which originate from embryonic stem cells and constitute the totality of the body's tissues and organs of multicellular organisms.
Therefore, we can conclude that body cells are those cells responsible for the growth of organs and tissues and gametes are each of the sex cells that fuse during fertilization.

Actin and myosin are both firm contractile protein filaments, the actin form the thin filaments, and myosin form thick filaments.
