3. Explain photosynthesis and write its equation. Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy, in the form of glucose. This process uses carbon dioxide and water as raw materials, with oxygen being released as a byproduct. Chlorophyll, a green pigment, absorbs the light energy needed for this reaction. The equation for photosynthesis is: $$6\text{CO}_2 + 6\text{H}_2\text{O} + \text{Light Energy} \longrightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2$$ $$\boxed{\text{Carbon dioxide} + \text{Water} + \text{Light Energy} \longrightarrow \text{Glucose} + \text{Oxygen}}$$ What's next?
