Consider the given reaction which occurs in the leaves of C4 plants.
Correct answer: D. Option D
- A. Option A
- B. Option B
- C. Opion C
- D. Option D
Explanation
The C4 cycle, also known as the Hatch-Slack pathway, has two main steps: initial carbon fixation in mesophyll cells and the subsequent Calvin cycle in bundle sheath cells. As this reaction shows initial carbon fixation, it must occur in mesophyll cells. So D is correct.

About Plant Nutrition and Transport
Plants require macronutrients and micronutrients for growth, and mineral deficiencies produce recognizable symptoms. Transport involves water and minerals through xylem by transpiration pull, cohesion and adhesion, while phloem translocates sugars from sources to sinks. Root pressure and transpiration are distinct mechanisms.
