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

The appropriate response is hypotonic. Plant cells are encased by an unbending cell divider. At the point when the plant cell is set in a hypotonic arrangement, it takes up water by osmosis and begins to swell, yet the cell divider keeps it from blasting. 
On the off chance that a plant cell is set in a hypertonic arrangement, the plant cell loses water and subsequently turgor weight by plasmolysis: weight declines to the point where the cellular material of the cell peels far from the cell divider, leaving holes between the cell divider and the film and influencing the plant cell to shrivel and fold.

The correct answer is:       [c]:   "organisms that are sensitive to changes in temperature would die. "
