Question

the function of the plasma membrane is to ___

o provide energy for the cell

o break down macromolecules, damaged organelles, or bacteria

o control what comes in and out of the cell

Explanation:

The plasma membrane is a selectively - permeable barrier. It regulates the movement of substances such as ions, nutrients, and waste products between the cell and its external environment. It does not provide energy for the cell (that's the role of mitochondria), nor does it break down macromolecules etc. (that's the role of lysosomes).

Answer:

control what comes in and out of the cell
