QUESTIONS AND ANSWERS 2026
- 2027
Tonicity - ANSWERS-described a comparisoin between two solution
hypotonic solution - ANSWERS-Solute concentration is less than that
inside the cell; cell gains water
hypertonic solution - ANSWERS-Solute concentration is greater than
that inside the cell; cell loses water
isotonic solution - ANSWERS-a solution whose solute concentration is
equal to the solute concentration inside a cell
What happens to a cell when placed in a hypotonic solution?
A) Net movement of water into the cell increases
B) Net movement of water out of the cell increases
C) The rates of water movement into and out of the cell are equal -
ANSWERS-A) Net movement of water into the cell increases
Osmosis - ANSWERS-Diffusion of water through a selectively
permeable membrane

QUESTIONS AND ANSWERS 2026
- 2027
-water diffuses from lower solute concentration to higher
what happens to a plant cell in a hypotonic solution - ANSWERS-swells
until the wall opposed uptake; the cell is now turgid (firm)
what happens to a plant cell in isotonic - ANSWERS-it becomes flaccid
what happens to a plant cell in a hypertonic enviornment - ANSWERS-
plant loses water, plasmolysis (shriveled)
what happens to a animal cell in a hypotonic solution - ANSWERS-
explodes
