Which solution would most likely cause a plant placed in it to become firmer and more rigid

Question

Hyperton hypotonic isotonic osomotic

Answer 1

For a plant to become more rigid, it would have to take in water. Water diffuses (a process called osmosis) from areas where there is a lot of water (and less solute, so hypotonic) to areas where there is not as much water (and more solute, so hypertonic). Therefore, for water to enter the plant, there would have to be less solute outside the plant, and your solution would have to be hypotonic. If you put the plant in isotonic solution, water will still move in and out but there will be no net change. Putting the plant in hypertonic solution would cause water to leave the plant, resulting in its shriveling.
