Question

Water crosses the cell membrane in both directions. If the amount going out is more than the amount going in, then the cell wall will [1 Mark] (a) Swell up because of plasmolysis (b) Stay the same size because of end-osmosis (c) Shrinks because of end-osmosis (d) Shrinks because of plasmolysis

Answer 1

Answer:

Most biological membranes are more permeable to water than to ions or other solutes, and water moves across them by osmosis from a solution of lower solute concentration to one of higher solute concentration. Animal cells swell or shrink when placed in hypotonic or hypertonic solutions, respectively.
