WebWhen stomata are open, however, water vapor is lost to the external environment, increasing the rate of transpiration. Therefore, plants must maintain a balance between efficient … WebJun 8, 2024 · The air space found between the spongy parenchyma cells allows gaseous exchange between the leaf and the outside atmosphere through the stomata. In aquatic plants, the intercellular spaces in the spongy parenchyma help the leaf float. Both layers of the mesophyll contain many chloroplasts.

Role of Stomata in Transpiration - Agri learner

WebAug 27, 2024 · Sunken stomata, as in adelfa or Nerium oleander, also lessen the rate of transpiration by sheltering the boundary layer from wind movement. Likewise, the presence of dry epidermal hairs or pubescence on the leaf surfaces tends to lessen the rate of transpiration by acting as windbreaks. WebC 4 plants reduce the need to frequently open stomata by creating a high carbon dioxide concentration in the bundle sheath cells, which conduct the Calvin cycle. Regardless of photosynthetic pathway, plants can open and close stomata to regulate transpiration rate … how many people work in the film industry
