Excited electrons from photo system-II are captured by:
Correct answer: B. PQ
- A. PC
- B. PQ
- C. Cytochrome-b
- D. Pentamerous
Explanation
Plastoquinone (PQ) is the correct answer as it accepts excited electrons from photosystem-II and transfers them down the electron transport chain. Plastocyanin (PC) and Cytochrome-b are involved in the electron transfer process but do not directly capture excited electrons like plastoquinone does. The term 'Pentamerous' is unrelated to the process of capturing excited electrons in photosynthesis.

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.
