which cells undergo mitosis and which undergo meiosis?

unicellular organisms, liver cells, sperm cells, brain cells, egg cells and skin cells

Unicellular organisms typically undergo mitosis as a form of asexual reproduction. Liver cells, skin cells, and brain cells in multicellular organisms also undergo mitosis for growth, repair, and replacement of damaged cells.

On the other hand, meiosis occurs in cells that give rise to reproduction, such as sperm cells and egg cells. Sperm cells are produced through spermatogenesis in males, and egg cells are produced through oogenesis in females. Meiosis is responsible for the formation of gametes (sex cells) with half the number of chromosomes as compared to the parent cell.
