Question

In a cell, what is the function of the cell membrane?

Answer 1

the semipermeable membrane surrounding the cytoplasm of a cell.

Step-by-step explanation:

The cell membrane controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules.

Answer 2

The cell membrane essentially controls what enters and leaves the cell. The membrane is composed of a phospholipid bilayer, which is hydrophobic, and therefore most soluble substances (anything that's polar or dissolves like water or ions) cannot enter directly through the membrane
