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. WebOct 4, 2024 · Bundle sheath cells are part of the Kranz leaf anatomy that is characteristic of C4 plants.
