what is stomata?give two functions of stomata.
Answers
Stomata are tiny openings or pores in plant tissue that allow for gas exchange. Stomata are typically found in plant leaves but can also be found in some stems. Specialized cells known as guard cells surround stomata and function to open and close stomatal pores. Stomata allow a plant to take in carbon dioxide, which is needed for photosynthesis. They also help to reduce water loss by closing when conditions are hot or dry. Stomata look like tiny mouths which open and close as they assist in transpiration.
Answer:
Stomata are small adjustable pores in the leave surface that enable gas exchange. Open stomata enable the uptake of carbon dioxide for photosynthesis, while closure prevents excessive loss of water during drought. During evolution, stomata enabled plants to survive in dry environments.
