Biology

The correct function of the cell membrane in prokaryotic cells is: C.To regulate the entry and exit of substances.

The cell membrane (also known as the plasma membrane) in prokaryotic cells acts as a selective barrier, controlling the movement of ions, nutrients, gases, and waste products in and out of the cell. This helps maintain the internal environment of the cell, ensuring it stays within the necessary conditions for cellular processes to occur.

Other options:

A.To store genetic material: The genetic material (DNA) is stored in the nucleoid region, not in the cell membrane.
