Question

which solution would most likely cause a plant placed in it to become firmer and more rigid?
hypertonic
hypotonic
isotonic
osmotic

Explanation:

Plant cells gain water and become turgid (firmer and more rigid) in a hypotonic solution due to osmosis. In a hypotonic solution, the solute concentration outside the cell is lower than inside, so water moves into the cell.

Answer:

B. hypotonic
