Stomata play a significant role in transpiration by allowing water vapor to escape from the plant through their pores. The opening and closing of stomata regulate the rate of transpiration, helping to maintain water balance within the plant.

Stomata contribute to the process of transpiration in plants by regulating the release of water vapor. During transpiration, water evaporates from the moist surfaces inside the plant to the surrounding atmosphere through the stomatal pores. The opening and closing of stomata, controlled by the guard cells, influence the rate of transpiration. When stomata open, water vapor escapes, creating a negative pressure that pulls more water from the roots through the plant’s vascular system. This continuous flow of water maintains plant hydration, facilitates nutrient transport, and contributes to cooling the plant. Stomata thus play a pivotal role in the water balance and overall health of plants.
