What is photosynthesis?
Photosynthesis is the process where plants use sunlight, water, and carbon dioxide from the air to make sugar (their food) and release oxygen as a waste product. Think of it as a factory: sunlight powers the machinery, water and CO₂ are the raw materials, and sugar is what the plant stores to grow and survive. Does that match what you were trying to explain before?
Plants convert light energy into chemical energy stored in glucose by splitting water molecules and fixing atmospheric carbon dioxide.
A factory runs on fuel that was made elsewhere; a plant captures and converts energy in real time, and the "waste" oxygen is essential to most life on Earth.
