Give a comparison between Anatomy of leaf in C3 and C4 plants
The plants which use C3 carbon fixation pathway and the first product of carbon dioxide fixation is a 3-carbon organic compound, 3-phosphoglycerate, are termed as C3 plants. The plants in which the first product of carbon dioxide fixation is a 4-carbon organic compound, oxaloacetate, are termed as C4 plants. Anatomy of leaf – C4 plants The arrangement of mesophyll and bundle sheath cells in the leaf of C4 plants is different from C3 plants. The parenchymatous cells which are a type of ground tissue present in the leaf are called mesophyll cells. The cells surrounding the vascular bundles is called the bundle sheath cells. In C4 plant these mesophyll cells are clustered around the bundle sheath cells and forms a shape which is similar to the wreath. This arrangement seen in the leaf of C4 plants is called Kranz
