Students have asked these similar questions
What is meant by concentration gradient? Is it correct to refer to “concentration gradient of water”?
why does water move inward in a hypotonic solution?
What general conclusion can you make concerning the movement of water? There is always a net movement of water by osmosis toward (a) an isotonic solution, (b) a hypotonic solution, or (c) a hypertonic solution.

- Answer itarrow_forwardi just answered a hw question that i was a little confused on. i answered it but am not fully sure if it's correct. so can you take a look at check if my answer is correct and if it's not, then a explaintion would be helpful. Would you expect water molecules to move faster when there is a HIGH concentration gradient or a LOW concentration gradient? Water molecules would move faster when there is a high concentration gradient because the pressure for the molecules in the high concentration to reach equilibrium increases since there are more molecules there than in the low concentration. So as the molecules move down the concentration gradient faster to equalize the concentration on both sides due to the increased pressure, the rate of diffusion increases.arrow_forwardWhat are some other biological examples of solutes affecting water potential and therefore movement of water in a living organism? Find examples in both plant and animal.arrow_forward
