In c4 plants the bundle sheath cells are

WebJun 11, 2024 · Most C 4 plants have special leaf anatomy (called Kranz anatomy) in which the vascular bundles are surrounded by bundle sheath cells. The Kranz anatomy facilitates the metabolite exchange between the two different cell types, specifically the mesophyll cells and the bundle sheath cells. WebApr 11, 2024 · Bundle sheath cells are a type of photosynthetic cells that occur covering the vascular bundle of C4 plants. The main significant feature of the bundle sheath cells is the presence of chloroplasts close to the vascular cells. However, the chloroplasts of the bundle sheath cells are fewer. In the meanwhile, they contain fewer or no grana.
