How does the plant obtain carbon dioxide for photosynthesis?

Plants obtain carbon dioxide for photosynthesis primarily through tiny pores called stomata. Stomata are present on the surface of leaves and other green parts of the plant. Carbon dioxide from the surrounding environment diffuses into the leaf through these stomatal openings. The exchange of gases, including the intake of carbon dioxide, occurs through stomata during photosynthesis. However, it is noteworthy that gaseous exchange, including carbon dioxide uptake, also takes place across the surfaces of stems and roots. Stomata regulate this crucial process, allowing plants to efficiently assimilate carbon dioxide for the synthesis of carbohydrates in the presence of sunlight and chlorophyll.
