what is the main function of the cell membrane in a plant cell?\nto use energy from sunlight to make sugar\n\nto break down sugar and release energy that the cell can use\n\nto give strength and stiffness to the cell\n\nto control which substances enter and leave the cell

what is the main function of the cell membrane in a plant cell?\nto use energy from sunlight to make sugar\n\nto break down sugar and release energy that the cell can use\n\nto give strength and stiffness to the cell\n\nto control which substances enter and leave the cell

Answer

Brief Explanations:

  • Analyze each option:
    • "to use energy from sunlight to make sugar" is the function of chloroplasts (photosynthesis), not the cell membrane.
    • "to break down sugar and release energy that the cell can use" is the function of mitochondria (cellular respiration), not the cell membrane.
    • "to give strength and stiffness to the cell" is the function of the cell wall (in plant cells), not the cell membrane.
    • "to control which substances enter and leave the cell" matches the known function of the cell membrane (selective permeability).

Answer:

The option "to control which substances enter and leave the cell" (the fourth option in the list)
