Question

what is the main function of the cell membrane in a plant cell? to contain the information that the cell uses for growth and activities to give strength and stiffness to the cell to control which substances enter and leave the cell to use energy from sunlight to make sugar

Explanation:

• The first option is incorrect because the cell's genetic information is stored in the nucleus, not the cell membrane.
• The second option is incorrect as the cell wall (not the cell membrane) provides strength and stiffness to plant cells.
• The third option is correct. The cell membrane is a selectively permeable barrier that controls the movement of substances (like nutrients, waste, etc.) into and out of the cell.
• The fourth option is incorrect because photosynthesis (using sunlight to make sugar) occurs in the chloroplasts, not the cell membrane.

Answer:

to control which substances enter and leave the cell
