The function of stomata in photosynthesis is gas exchange. Stomata are tiny openings on the surface of plant leaves and stems that allow for the exchange of gases, particularly the intake of carbon dioxide (CO2) and the release of oxygen (O2). This exchange of gases is crucial for photosynthesis to occur, as carbon dioxide is a necessary ingredient for the process while oxygen is a byproduct.
The correct answer is "gas exchange." Stomata are tiny openings, usually found on the underside of a plant's leaves, which allow for the exchange of gases during photosynthesis. They actually enable the plant to take in carbon dioxide from the atmosphere, which is a key ingredient for photosynthesis, and release oxygen as a byproduct. To find this answer, it helps to have a basic understanding of photosynthesis and the role of stomata in the process.
