DENDROLOGY

Detailed explanation-1: -Its prime function is to exchange the gases by closing and opening the pores in the leaves. It assists in eradicating excess water from the leaves. It removes oxygen and takes in carbon dioxide at the time of photosynthesis.

Detailed explanation-2: -Stomata are the specialized pores or openings present in the epidermis of plant cells, which play a crucial role in gaseous exchange during the process of photosynthesis.

Detailed explanation-3: -Stomata regulate gas exchange between the plant and environment and control of water loss by changing the size of the stomatal pore. This stomatal movement is affected by several environmental stimuli, such as relative humidity, CO2 concentration, and light intensity.

Detailed explanation-4: -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.

Detailed explanation-5: -stoma (plural stomata) A tiny opening in the surface of a plant leaf or stem. It allows gases and water vapor to escape. Some plants close their stomata at night. Other plants-those living in very dry areas such as deserts-close them during the day to keep water inside.
