Give comparison between the following: (c) Anatomy of leaf in C३ and C4 plants
Explanation In C₄ plants kranz anatomy is present whereas it is absent in the case of C₃ plants. In C₄ plants rubisco is present in bundle sheath cells whereas in C₃ plants it is present in mesophyll cells. In C₄ plants photorespiration is absent whereas in C₃ plants photorespiration is present. In C₄ plants the chloroplasts are dimorphic whereas in C₃ the chloroplasts are not dimorphic.Final Answer C₃ and C₄ plants cannot be differentiated by external morphology. In C₃ plants, a three-carbon compound is a first formed product whereas in C₄ plants four-carbon compound is a first formed product. Mesophyll cells present in C₃ plants have intercellular space whereas in C₄ plants mesophyll cells have no intercellular space
