A)molecules from a high concentration to a low concentration.
B)water through a selectively permeable membrane to a solution containing a higher concentration of impermeant solute.

D)ions from a low pressure region to a high pressure region through a selectively permeable membrane.

Question

Quizplus · Accepted Answer

Osmosis is the movement of water through a selectively permeable membrane to a solution containing a higher concentration of impermeant solute. This process results in the equalization of solute concentration on both sides of the membrane. Option A describes diffusion, which is the movement of molecules from high to low concentration. Option C is the opposite of osmosis and would result in the movement of water out of the cell. Option D describes reverse osmosis, which is the movement of water from a high pressure region to a low pressure region through a selectively permeable membrane.
