In leaves of C ₄ -plants malic acid synthesis during CO ₂ -fixation occurs in

Options

  1. Aepidermal cells
  2. Bmesophyll cells
  3. Cbundle sheath
  4. Dguard cells

Correct answer

B. mesophyll cells

Step-by-step solution

C ₄ -plants show Kranz anatomy. In the leaves of C ₄ -plants the vascular bundles are surrounded by bundle sheath of parenchymatous cells, which in turn are surrounded by mesophyll cells. In C ₄ -plants the Hatch and Slack pathway involves two carboxylation reaction one taking place in chloroplast of mesophyll cells and other in chloroplast of bundle sheath cells. The initial CO ₂ fixation occurs in mesophyll cells where primary CO ₂ acceptor is phosphoenol pyruvate and formed oxaloacetate. The oxaloacetate is redu
