Plants have many crucial roles on our planet, and among these is the gas exchange that happens within their leaves. As plants take in carbon dioxide from our atmosphere, they release oxygen and retain the carbon. In this lesson, students will investigate leaves up close to look for the structures responsible for gas exchange.
