Question

what happens if a plant cell is placed in a hypotonic solution?
a become turgid (firm)
b swell and burst
c plasmolyzed
d no change

Explanation:

In a hypotonic solution, the water potential outside the plant cell is higher than inside. Water enters the cell via osmosis. Plant cells have a rigid cell wall that prevents bursting. Instead, the cell becomes turgid (firm) as the vacuole fills with water, exerting pressure against the cell wall. Option b is incorrect because the cell wall stops bursting. Option c (plasmolyzed) occurs in hypertonic solutions, and option d (no change) is wrong as osmosis occurs.

Answer:

a. become turgid (firm)
