Carbon dioxide for photosynthesis mainly enters the plant through what?
Answer and explanation
Correct answer: Through stomata
Carbon dioxide is a gaseous raw material needed to make glucose during photosynthesis. Tiny pores called stomata, found mainly on leaf surfaces, open and close to regulate gas exchange; carbon dioxide diffuses through them into the leaf tissues. Therefore, option A is correct. Roots absorb water, while petals and seed coats are not the main pathways for photosynthetic gas exchange.
