The cyclic flow of C4 photosynthesis produces:
Correct answer: B. ATP
- A. ATP and CO2
- B. ATP
- C. Only CO2
- D. Only Oxygen
Explanation
Linear electron flow (LEF) in photosynthesis produces both ATP and NADPH, and the cyclic electron flow (CEF) around photosystem I has been shown to produce only ATP.

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.
