Question

3 multiple choice 1 point which of the following describes the plasma membrane? a single - layered membrane that surrounds the nucleus of the cell a membrane composed of tiny shelves or cristae a phospholipid bilayer surrounding the cell a double layer of protein enclosing the plasma

Explanation:

The plasma membrane is a fundamental cell - structure. It is a phospholipid bilayer that surrounds the cell, controlling the movement of substances in and out of the cell. The first option describes the nuclear membrane, not the plasma membrane. Cristae are found in mitochondria, not in the plasma membrane. And the plasma membrane is not a double - layer of protein enclosing the plasma.

Answer:

a phospholipid bilayer surrounding the cell
