Question

1. which function within the cell is performed by the cell membrane? a. creating food and energy b. collecting and storing water c. containing genetic material d. controlling what enters and leaves the cell

Explanation:

To determine the function of the cell membrane, we analyze each option:

• Option A: Creating food and energy is the role of chloroplasts (in plants) or other energy - producing organelles, not the cell membrane.
• Option B: Collecting and storing water is a function of vacuoles, not the cell membrane.
• Option C: Containing genetic material is the function of the nucleus, which holds DNA (the genetic material).
• Option D: The cell membrane is a selectively permeable barrier. It regulates the movement of substances, controlling what enters and leaves the cell. This is a well - known function of the cell membrane.

Answer:

D. controlling what enters and leaves the cell
