Question

Select the correct statement about osmosis. a. Osmotic equilibrium cannot be reached unless solute concentrations equalize across the membrane. b. If a dead cell is placed in a solution hypotonic to the cell contents, osmosis will not occur. c. Osmosis is the diffusion of water molecules across a selectively permeable membrane.

Answer 1

Answer:

c. Osmosis is the diffusion of water molecules across a selectively permeable membrane.

Explanation:

Osmosis is the passive transport of water molecules from the region of their higher concentration to that of lower concentration through a semi-permeable membrane. Osmosis does not include the movement of solutes. When two solutions with different concentrations of solutes are separated by a semi-permeable membrane, water moves through the membrane from a hypotonic solution to the hypertonic solution until equilibrium is obtained. This process is called osmosis.
