When the stomata on a plant's leaves are open, several key processes occur:
1. Carbon dioxide enters the leaves: Stomata are small pores located on the underside of leaves. When they are open, carbon dioxide from the air can diffuse into the leaf through these pores.
2. Sunlight is able to enter the leaves: Open stomata allow sunlight to reach the chloroplasts inside the leaf cells. This sunlight is essential for the process of photosynthesis to take place.
3. Photosynthesis takes place: With carbon dioxide entering the leaves and sunlight reaching the chloroplasts, photosynthesis can occur. During photosynthesis, plants convert carbon dioxide and water into glucose (a type of sugar) and oxygen. This process is crucial for the plant's growth and survival.
In summary, when the stomata on a plant's leaves are open, carbon dioxide enters the leaves, sunlight can reach the chloroplasts, and photosynthesis occurs, leading to the production of glucose and oxygen.
