When the Guard Cells of a Leaf Shrink, How Do

Question

When the guard cells of a leaf shrink, how do the stomata change?
A) They open.
B) They close.
C) They perform photosynthesis.
D) They die.

Accepted Answer

When the guard cells of a leaf shrink, the space between them decreases, causing the stomata to close. Similarly, when the guard cells become turgid, the stomata open. Therefore, the correct choice is B, since the shrinking of guard cells leads to the closure of stomata.
