Which of the following characteristics out of I, II and III are exhibited by C ₄ plants? I. Kranz anatomy. II. The product of photosynthesis is oxalo acetic acid. III. Both PEP carboxylase and ribulose-bis phosphate carboxylase act as carboxylating enzyme. Choose the corrent option.

Options

  1. AI and II, but not III
  2. BII and III, but not I
  3. CI and III, but not II
  4. DAll of these

Correct answer

D. All of these

Step-by-step solution

C ₄ plants have an alternative CO ₂ fixation pathways called Hatch and Slack cycle where OAA, a 4C compound is the first stable product. These plants have Kranz anatomy in leaf.
