How do stomata play roles in both photosynthesis and transpiration?
Answer and explanation
Correct answer: They help gas entry and water vapour loss
Stomata are small pores, usually in the epidermis of leaves, that regulate exchange with the atmosphere. Carbon dioxide enters through them and is required for photosynthesis; oxygen produced during photosynthesis can also leave. Water evaporates from internal leaf surfaces and exits mainly through these pores, producing transpiration. Therefore A correctly describes both roles. The other options refer to storage or animal functions unrelated to stomata.
