In the leaves of C4\mathrm{C}_4 plants, malic acid formation during CO2\mathrm{CO}_2 fixation occurs in the cells of:

Options

  1. Abundle sheath
  2. Bphloem
  3. Cepidermis
  4. Dmesophyll.

Correct answer

D. mesophyll.

Step-by-step solution

C4\mathrm{C}_4 plants have Kranz anatomy consisting of mesophyll and bundle sheath cells. In mesophyll cells, PEP functions as CO2\mathrm{CO}_2 acceptor and forms oxalic acid. Later, oxalic acid is reduced to malic acid. Finally, malic acid is transferred to bundle sheath cells.
