Final answer:
In order to vary the capacity of an absorption plant, you should regulate the opening and closing of stomata. This allows plants to control the rate of gas exchange and manage their absorption capacity based on their energy and water needs.
Step-by-step explanation:
In order to vary the capacity of an absorption plant, you should regulate the opening and closing of stomata. Stomata are tiny openings on the surface of plant leaves that allow for gas exchange, including the absorption of carbon dioxide and the release of oxygen and water vapor. By controlling the opening and closing of stomata, plants can control the rate of gas exchange and therefore regulate their absorption capacity.
For example, when a plant needs to increase its absorption capacity, it can open its stomata wider to allow more carbon dioxide to enter for photosynthesis. On the other hand, when a plant needs to conserve water, it can close its stomata to reduce the loss of water vapor through transpiration.
Regulating stomata opening and closing provides plants with the flexibility to adjust their absorption capacity according to their needs for energy production and water conservation.
