उत्तर
The leaves of C4 plants have a special anatomy called Kranz anatomy. This makes them different from C3 plants. Special cells, known as bundle-sheath cells, surround the vascular bundles. These cells have a large number of chloroplasts. They are thick-walled and have no intercellular spaces. They are also impervious to gaseous exchange. All these anatomical features help prevent photorespiration in C4 plants, thereby increasing their ability to photosynthesise.

The anatomy of the leaves of C3 plants is not of the Kranz type. Pillar tissue is found in the mesophyll in its leaves. same type of chlorophyll was found in all the cells. Let's go. Both pigment systems are found in the photosynthesis system.
