Detailed explanation-1: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

Detailed explanation-2: -Oxygen (O2) is evolved during photosynthetic electron transport when water is split by the oxygen-evolving complex to provide protons and electrons to the chloroplastic electron chain, thereby generating ATP and NADPH-the energy source and reducing power for plant metabolism.

Detailed explanation-3: -Oxygen (O) is responsible for cellular respiration in plants. This element plays a critical role in photosynthesis and is both stored for energy and released as a byproduct.

Detailed explanation-4: -In photosynthesis, solar energy is harvested and converted to chemical energy in the form of glucose using water and carbon dioxide. Oxygen is released as a byproduct.

Detailed explanation-5: -Glucose: Glucose is a simple food that is prepared first in the process of photosynthesis. The end products of photosynthesis are glucose and oxygen and the glucose is converted to starch. Starch is the food that gets stored in plant leaves.
