which function does the stomata perform in photosythesis
The stomata perform several functions in photosynthesis:
1. Gas exchange: Stomata are small openings or pores present on the leaves and stems of plants. They allow the exchange of gases, such as carbon dioxide and oxygen, between the plant and its environment. During photosynthesis, plants take in carbon dioxide through stomata and release oxygen as a byproduct.
2. Regulation of water loss: Stomata play a crucial role in controlling water loss through transpiration. When stomata are open, water vapor escapes from the plant's tissues into the surrounding atmosphere. The opening and closing of stomata help regulate the amount of water lost, preventing excessive drying out of the plants.
3. Regulation of heat: Stomata also aid in the regulation of temperature within the plant. When the stomata open, they release water vapor, which cools the plant as it evaporates. This process is known as evaporative cooling and helps prevent overheating of the plant.
In summary, stomata allow for gas exchange, regulate water loss, and assist in temperature regulation within plants during photosynthesis.
