Which of the following statements about osmosis is correct?
a. If a cell is placed in an isotonic solution, more water will enter the cell than leaves the cell.
b. Osmotic movement of water into a cell would likely occur if the cell accumulates water from its environment.
c. The presence of aquaporins (proteins that form water channels in the membrane) should speed up the process of osmosis.
d. If a solution outside the cell is hypertonic compared to the cytoplasm, water will move into the cell by osmosis.
e. Osmosis is the diffusion of water from a region of lower water concentration to a region of higher water concentration.
