Question

a plant cell remains unchanged in shape or size when it is kept in a solution. what kind of solution is it? a distilled water b isotonic solution c hypotonic solution d hypertonic solution

Explanation:

A plant cell’s shape/size stays unchanged when there is no net movement of water across its membrane. An isotonic solution has the same solute concentration as the cell’s cytoplasm, so water moves equally in and out. Distilled water and hypotonic solutions cause water to enter the cell (swelling), while hypertonic solutions cause water to leave (shrinking).

Answer:

B. isotonic solution
