Correct answer: A. Thylakoid
- A. Thylakoid
- B. Stroma
- C. Lamella
- D. Membrane
Explanation
The light reaction takes place in the thylakoid membranes. In the light reaction, the light is absorbed and energy is used to drive electrons from water to generate NADPH and to drive protons across the membrane.

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.
