Question 118

An animal cell is placed in a sufficiently concentrated external solution. Which change is expected as water moves by osmosis?

  1. It gains water and becomes turgid.
  2. Its cell wall prevents any volume change.
  3. It loses water and shrinks.Correct answer
  4. Its membrane pulls away from a cellulose wall.

Explanation

Water leaves the animal cell for the more concentrated surroundings, so the cell loses volume and shrinks. Turgidity requires a plant cell wall resisting expansion and therefore does not describe this animal cell.
