WebOn the other hand, C 4 plants are defined as the plants that use the C 4 pathway or Hatch-Slack pathway during the dark reaction. The leaves possess kranz anatomy, and the chloroplasts of these plants are dimorphic. About 5% of plants on earth are C 4 plants. Let us have a detailed look at the important difference between C 3 and C 4 plants. WebSecond, C4 plants have specialized leaf anatomy with two different types of photosynthetic cells: mesophyll cells (on the exterior of the leaf, near stomata) and bundle sheath cells (in the interior of the leaf, far away from stomata). Rubisco is located in bundle sheath cells, but not in mesophyll cells. Here’s how all this works:
