What will be the effect on food formation if stomata remain closed during photosynthesis?
Answer and explanation
Correct answer: Carbon dioxide entry will decrease and food formation will reduce
The governing concept is photosynthesis and the role of stomata in gas exchange. Carbon dioxide, a raw material for making glucose, normally enters the leaf through stomatal pores. If the stomata remain closed, carbon-dioxide entry becomes limited, so the rate of photosynthesis and food formation generally decreases. Option A is correct; closure does not increase oxygen entry, instantly stop root absorption, or destroy chlorophyll.
