Here's how it works:
1. Sunlight provides the energy needed for the plant to convert carbon dioxide (CO2) and water (H2O) into glucose (sugar) and oxygen (O2).
2. This process happens in the chloroplasts of the leaf, which contain chlorophyll, the pigment that absorbs sunlight.
3. The glucose produced is the plant's food source, providing it with the energy it needs to grow and function.
4. The oxygen is released as a byproduct of photosynthesis.
So, the sun's light energy is the key ingredient that allows leaves to produce their own food and sustain life.
