Explanation:

The plasma membrane is a selectively permeable barrier. It uses various transport mechanisms (such as passive diffusion, facilitated diffusion, active transport) to regulate what substances can enter or leave the cell. Centrosomes and centrioles are involved in cell division. Ribosomes are for protein synthesis. The rough endoplasmic reticulum (rough ER) is associated with protein production and modification.

plasma membrane
