In light dependent reactions of photosynthesis, the cyclic electron transport yields only:
Correct answer: A. ATP
- A. ATP
- B. Water
- C. Oxygen
- D. NADPH
Explanation
The cyclic electron transport in the light-dependent reactions of photosynthesis specifically produces ATP. This is because the electrons are cycled back to the photosystem, allowing for the generation of ATP without the production of NADPH or oxygen. Water is consumed, not produced, in these reactions, as it is split to provide electrons. Oxygen is released as a by-product of the water-splitting process but only in non-cyclic electron transport. NADPH is also a product of non-cyclic electron transport, not cyclic.

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.
