WebAug 15, 2024 · Stomata allow a plant to take in carbon dioxide, which is needed for photosynthesis. They also help to reduce water loss by closing when conditions are hot or dry. Stomata look like tiny mouths which open and close as they assist in transpiration. Plants that reside on land typically have thousands of stomata on the surfaces of their … WebWhen stomata are open, however, water vapor is lost to the external environment, increasing the rate of transpiration. Therefore, plants must maintain a balance between efficient photosynthesis and water loss. Plants have evolved over time to adapt to their local environment and reduce transpiration (Figure 5).
