stomata Example in a sentence
Stomata, microscopic pores on plant leaves, facilitate gas exchange and water regulation.
The stomata are guarded by two cells called guard cells, which control their opening and closing.
When stomata open, they allow carbon dioxide to enter the leaf for photosynthesis.
Simultaneously, stomata facilitate the release of oxygen and water vapor as transpiration occurs.
The opening and closing of stomata is a critical process regulated by factors like light intensity, temperature, and water availability.
Under bright sunlight, stomata typically open to maximize photosynthesis.
In darkness, stomata close to conserve water and prevent excessive water loss.
When water is scarce, stomata close to reduce transpiration and protect the plant from dehydration.
Stomata density varies across different plant species and leaf types, influencing water and gas exchange capacities.
Understanding stomatal functioning is essential for plant physiologists studying plant growth, photosynthesis, and water relations in various environmental conditions.
