WebApr 11, 2024 · Prior to the cyclic CO 2 treatments, the steady-state responses of leaf gas exchange and fluorescence to CO 2 were determined. In four of the five species, in which stomatal conductance decreased with increasing CO 2, the cyclic CO 2 treatments reduced stomatal conductance. In those species, both photosynthesis and the photochemical … WebThe main functions of stomata are: Gaseous exchange- Stomatal opening and closure help in the gaseous exchange between the plant and surrounding.

In plants, oxygen and carbon dioxide diffuse through the stomata and the intercellular spaces of the leaves, and the lenticels of the bark. In woody plants, the stem is covered with bark. ADVERTISEMENTS: Lenticels are small openings in the pits of the bark.
Web2 properties of leaves that assist gas exchange. most gas exchange in plants occurs through the leaves, but some occurs through the stems and roots. Leaves are very thin with a high surface area and this assists gas exchange by diffusion. Aquatic environment - water loss. water loss in an aquatic environment is not a problem for plants. WebJan 14, 2024 · Gaseous exchange occurs in the root hair of young terrestrial plants. Oxygen in the air spaces in the soil dissolves in the film of moisture surrounding soil particles and diffuses into the root hair along a concentration gradient. It diffuses from root hair cells into the cortex where it is used for respiration.
WebWhen open, stomata allow CO2 to enter the leaf, and allow for water and oxygen to escape. In addition to opening and closing the stomata, plants may exert control over their gas exchange rates by varying stomata density in new leaves when they are produced (such as in the spring or summer). The more stomata per unit area is the stomata density.
