What do all cells in my hand have?

All cells in your hand contain a nucleus, which houses the cell's genetic material (DNA). They also have a cell membrane that regulates what enters and exits the cell. Additionally, cells in your hand contain cytoplasm, where various organelles, such as mitochondria and ribosomes, function to support cellular processes. Furthermore, they all share essential cellular components like ribosomes, endoplasmic reticulum, and Golgi apparatus for protein synthesis and processing.
