What happens during the day in leaves with respect to gas exchange?
Understand the Problem
The question is asking about the process of gas exchange in leaves during the daytime, specifically what gases are produced or consumed by the leaves. This relates to photosynthesis and respiration in plants.
Answer
During the day, leaves engage in both respiration and photosynthesis, exchanging oxygen and carbon dioxide through stomata.
During daylight, in leaves, both respiration and photosynthesis occur, resulting in the exchange of gases through stomata. Oxygen is produced and part of it is used for respiration while the rest diffuses out. Carbon dioxide diffuses into the leaf for photosynthesis.
Answer for screen readers
During daylight, in leaves, both respiration and photosynthesis occur, resulting in the exchange of gases through stomata. Oxygen is produced and part of it is used for respiration while the rest diffuses out. Carbon dioxide diffuses into the leaf for photosynthesis.
More Information
Leaves have specialized structures called stomata that open during the day to facilitate gas exchange necessary for photosynthesis, resulting in the uptake of carbon dioxide and release of oxygen.
Tips
A common mistake is to think that photosynthesis stops at any point during daylight while it actually continues as long as there is enough light.
