Each _ consists of a light-gathering antenna complex and reaction center
Correct answer: B. Photosystem
- A. Chlorophyll
- B. Photosystem
- C. Photon
- D. Electron
Explanation
Photosystem is the correct option because it refers to the functional unit in the chloroplasts of plants and cyanobacteria where the process of photosynthesis takes place. It consists of a light-gathering antenna complex that captures photons and a reaction center where the captured light energy is converted into chemical energy through the transfer of electrons.

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.
