to prevent excessive water loss by transpiration
Water lilies will have less. Water plants have stomata on the sides exposed to air. Or if totally submerged, there are no stomata present. A cactus is covered with stomata but not as much as average plants.
Yes, during a drought, plants close their stomata to conserve water and prevent excessive water loss through transpiration. This helps the plant maintain its hydration levels and survive the dry conditions.
Stomata density directly affects the rate of transpiration (water loss) in plants. Higher stomata density means more openings for water vapor to escape, leading to increased water loss. Conversely, lower stomata density reduces the rate of transpiration and helps plants conserve water.
Plants lose most of their water by transpiration through the stomata of the leaves.
Transpiration is the process by which plants give out water through the stomata.
Tiny openings on plant leaves are called stomata. Stomata are responsible for gas exchange, allowing plants to take in carbon dioxide for photosynthesis and release oxygen and water vapor.
they are called stomata
generally xerophytic plants have sunken stomata
Plants have stomata on the surface of their leaves. Stomata are small openings surrounded by specialized cells that regulate gas exchange and water loss. This allows for excess water to escape in the form of vapor during transpiration.
Evaporation of water through the stomata is called transpiration. It is a natural process where water vapor escapes from the plant leaves through small openings, the stomata. This loss of water helps plants cool down and facilitates the movement of nutrients and water from the roots to the leaves.
Plants do not keep their stomata open all the time because it would lead to excessive water loss through transpiration. Stomata need to close to prevent dehydration and maintain proper water balance within the plant. Additionally, closing stomata helps plants conserve energy and regulate gas exchange more efficiently.
Transpiration is the evaporation of cellular water (in the form of water vapour) from the stomata in the leaves of PLANTS. Humans are NOT plants.
