Detailed explanation-1: -The light-dependent reaction of photosynthesis utilizes water (H2O) and produces oxygen (O2). The light reactions of photosynthesis supply the Calvin cycle with carbon dioxide to produce sugars.

Detailed explanation-2: -In photosynthesis, oxygen, carbon dioxide, ATP, and NADPH are reactants. GA3P and water are products. In photosynthesis, chlorophyll, water, and carbon dioxide are reactants.

Detailed explanation-3: -In photosynthesis, a light-dependent reaction uses light energy from the sun to split water which has been taken in by the organism. Water, when split, gives oxygen, hydrogen, and electrons. These electrons move through structures in chloroplasts and, by chemiosmosis, make ATP.

Detailed explanation-4: -Many organisms, such as green plants, convert light energy into chemical energy through the mechanism of photosynthesis. In this process, green plants capture light energy and form organic compounds, which are rich in energy and oxygen (O) by using minerals, carbon dioxide (CO2), and water (H2O).
