After light triggers the activation proton pumps, what happens next in the leaf?
A) Chloride ions are pumped out of the guard cells.
B) Hydrogen ions are actively transported out of guard cells.
C) Potassium ions diffuse into guard cells.
D) Chloride ions diffuse out of guard cells.
E) Water moves by osmosis into guard cells.

Question

Quizplus · Accepted Answer

The activation of proton pumps in guard cells leads to the active transport of hydrogen ions (H+) out of the cells, creating an electrochemical gradient that facilitates the subsequent movement of potassium ions into the guard cells.
