In plant tissue, stomata are microscopic pores that facilitate gas exchange. Although some stems also have stomata, they are primarily seen in plant leaves. To open and close stomatal holes, specialized cells called guard cells to surround stomata.
- Stomata are openings in plant leaves that regulate the exchange of gases during photosynthesis, an activity essential to life as we know it.
- Gas fluxes and plant production are influenced by extrinsic elements like light, water, and CO2 availability as well as by the stoma pores' geometrical characteristics.
- The stomata close at night to prevent water loss when photosynthesis is not taking place.
- Stomata close throughout the day if the leaves are dehydrated, as may happen during a drought.
- It aids in water transpiration, or the plant's surplus water being lost. Stomatal water loss causes a suction pull, or upward pull, that aids in drawing water up from the roots. They contribute in return for gases.
