WebThe main function of stomata is to allow a plant to exchange gases with the surrounding atmosphere. In particular, stomatal openings allow the uptake of carbon dioxide, a key ingredient in photosynthesis. They also allow for the plant to release the oxygen gas that is a byproduct of photosynthesis.

WebBased on table 1, it is known that the average number of stomata in the adaxial is higher than in the abaxial section. The number of stomata is correlated to the density of stomata, higher number of stomata, higher density of stomata. The stomata index is a comparison of the number of epidermal cells in a certain unit of area. WebApr 12, 2024 · “The literature was able to show us that reducing the number of stomata could improve water use efficiency,” says Karavolias, “But at a cost.” Indeed, the loss of so many stomata also dramatically reduces the plant’s ability to do the exchange of carbon dioxide and oxygen that drives photosynthesis, plant growth, and plant yield. little bay south croydon menu
