In photosynthesis, oxygen molecules are formed as a by-product during:
Correct answer: A. Photolysis
- A. Photolysis
- B. Chemiosmosis
- C. Carbon fixation
- D. Cyclic phosphorylation
Explanation
In photosynthesis, oxygen is released during the photolysis of water, which occurs in the light-dependent reactions. Photolysis uses light energy to split water molecules into hydrogen ions, electrons, and oxygen. This process is essential for providing electrons for the electron transport chain and contributes to the formation of NADPH and 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.
