– The main reactants required for photosynthesis are carbon dioxide (CO₂), water (H₂O), and light energy. Chlorophyll is the pigment that captures light energy.
– The general equation for photosynthesis is: 6CO₂ + 6H₂O + Light Energy → C₆H₁₂O₆ (glucose) + 6O₂.
– Carbon dioxide is the source of carbon for synthesizing glucose.
– Water provides hydrogen atoms and electrons, and is also a source of oxygen which is released as a byproduct.
– Oxygen (O₂) is a product of photosynthesis, not a requirement for the process itself. Plants release oxygen into the atmosphere during photosynthesis.
