C4 Plant

C4 Plant

The picture above shows sugar cane, a member of C4 carbon fixation plants. C4 plants grow where high temperatures, and drought are common. C4 plants have adapted special types of leaves, which have bundle sheath cells surrounding the vascular bundles. They bind their carbon into a four carbon compound called Phosphoenolpyruvate inside their mesophyll cells and transported to the bundle sheath cells where it is transformed into a three carbon sugar and put through the C3 carbon fixation pathway.
