Kranz anatomy
The C4 plants have Kranz anatomy. The vascular bundle of the leaf is surrounded by one or more layer of chloroplast, containing cells (bundle sheath cells). The bundle sheath cells lack grana in their chloroplast while mesophyll cells have well developed grana. The mesophyll cells are specialized for light reaction and initial CO2 fixation during photosynthesis. The CO2 is finally fixed inside bundle sheath cell through Calvin cycle.
