If stomata do not close during water shortage, what main problem will the plant face?
Answer and explanation
Correct answer: Water loss will increase
The governing concept is stomatal regulation of transpiration. Stomata permit carbon dioxide entry and gas exchange, but open stomata also allow water vapour to diffuse out of leaves. During water shortage, failure to close them increases transpiration and can worsen dehydration, wilting, and loss of turgidity. Abscisic acid commonly promotes stomatal closure under water stress. Blood sugar, a spinal cord, and muscle contraction are irrelevant plant outcomes. Option A is correct.
