Question

the cell membrane, also known as the plasma membrane, separates the inside of the cell from the outside environment. it is a semipermeable barrier. the latin prefix semi - means half, and permeable means having pores or openings that substances can pass through. what is the significance of a semipermeable cell membrane? the cell membrane only allows certain substances to enter or leave the cell. the cell membrane allows all substances to enter or leave the cell. the cell membrane does not allow any substances to enter or leave the cell.

Explanation:

The term semi - permeable means only some substances can pass through. A semi - permeable cell membrane controls the movement of substances in and out of the cell, maintaining the cell's internal environment. It does not allow all substances to pass (otherwise it would be fully permeable) and does not block all substances (otherwise it would be impermeable).

Answer:

The cell membrane only allows certain substances to enter or leave the cell.
