Gas exchange in plants is dominated by the roles of carbon dioxide, oxygen and water vapor. CO 2 is the only carbon source for autotrophic growth by photosynthesis, and when a plant is actively photosynthesising in the light, it will be taking up carbon dioxide, and losing water vapor and oxygen. At night, plants respire, and gas exchange partly reverses: water vapor is still lost (but to a smaller extent), but oxygen is now taken up and carbon dioxide released.

WebJul 7, 2024 · How does gas exchange occur in plants? In plants, the exchange of gases takes place through stomata. Each of the stomata is surrounded by two guard cells, and these cells contain chloroplasts. A respiratory opening is found under each stoma, and the process of opening and closing of stomata depends on the presence of sugar and starch … WebDescribe the role of the stomata during gas exchange? Guard cells surround the stomata and regulate the opening and closing of the stomata, which allows for the exchange of gases to occur. During the day, the guard cells absorb water by osmosis, which makes them turgid and they can open the stomata. Thick inner walls split open.
