How do stomata affect 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. WebA group of pupils investigated the way in which the colour of light affects photosynthesis. The pupils: put a piece of pondweed into a test tube of water shone light from a lamp with a red light bulb onto the pondweed counted the bubbles of gas produced by the pondweed every minute for three minutes.

WebApr 15, 2024 · Third, it allows for oxygen to be expelled into the outside environment, a byproduct of photosynthesis that is no longer needed by the cell. While an open stoma is necessary for the plant to undergo photosynthesis, it comes with a negative side effect: water loss. Over 95% of a plant’s water loss occurs through the stoma via water vapor. WebThere are several ways of measuring the rate of photosynthesis in the lab. These include: the rate of oxygen output the rate of carbon dioxide uptake the rate of carbohydrate production These are...
WebThe stomata open and close according to the physiological needs of the leaf. In hot and arid climates the stomata may close to conserve water, but this closure limits the entry of … WebThe high temperature will make the plant close its stomata to reduce water loss by evaporation. If the stomata is closed, the oxygen from photosynthesis will build up inside the leaf while the carbon dioxide will …
WebIt does this by diffusing through small pores called stomata. At the same time oxygen moves out of the leaf through the stomata. This movement of gases in opposite directions is called gas exchange.
