Compared with a plant cell that has a few aquaporin proteins in its plasma membrane, a cell containing many aquaporin proteins will likely exhibit which of the following?

  • A: A faster rate of osmosis.
  • B: A lower water potential.
  • C: A higher water potential.
  • D: Accumulate water by active transport.

Explanation

Aquaporins are transport proteins in the plasma membrane that facilitate the rapid movement of water across the membrane by osmosis. A higher concentration of aquaporins means more channels for water to pass through, thus increasing the rate of osmosis.
