Which of the following characteristics is are exhibited by C4\mathrm{C}_4-plants? I. Kranz anatomy. II. The first product of photosynthesis is oxaloacetic acid. III. Both PEP carboxylates and ribulose biphosphate carboxylate act as carboxylating enzymes. The correct option is

Options

  1. AI and III, but not II
  2. BI and II, but not III
  3. CII and III, but not I
  4. DII and III

Correct answer

D. II and III

Step-by-step solution

C4\mathrm{C}_4-plants have an alternative CO2\mathrm{CO}_2 fixation pathway called Hatch and Slack cycle. These plants have Kranz anatomy in leaf, where vascular bundles are surrounded by bundle sheath. In C4\mathrm{C}_4 cycle light reaction occurs in, mesophyll chloroplast by PEP carboxylaes and the assimilation of CO2\mathrm{CO}_2 takes place in, i.e., dark phase in bundle sheath chloroplast by Rubisco.
