Question

Quizplus · Accepted Answer

The correct answer is D) Na⁺, which seems to be a placeholder for sodium ions (Na+). Sodium ions are less directly involved in the opening and closing of stomata compared to the other options. Ambient light levels (A) significantly influence stomatal opening, as do potassium ions (C, likely meant to represent K+), and turgor pressure (E), which is crucial for the change in shape of guard cells that open and close the stomata. Option B appears to be a placeholder or error and does not correspond to a known factor directly involved in stomatal movement.
