* Chlorophyll and Sunlight: Chlorophyll is a complex molecule found in the chloroplasts of plant cells. It absorbs light energy, primarily in the red and blue wavelengths of the visible spectrum.

* Reflected Light: Green light is not absorbed by chlorophyll as well, so it is reflected back to our eyes, making leaves appear green.

* Photosynthesis: The absorbed light energy powers photosynthesis, the process by which plants convert carbon dioxide and water into sugars (their food) and oxygen.

Think of it like this: Imagine shining a white light (containing all colors) onto a green leaf. The chlorophyll "eats" the red and blue colors, leaving the green color behind to bounce back and be seen.

Why are leaves other colors?

* Other pigments: Leaves contain other pigments besides chlorophyll, but these are often masked by chlorophyll's dominance. As temperatures drop in the fall, chlorophyll breaks down, revealing the yellow and orange pigments (carotenoids) that were already present in the leaf.

* Red and purple pigments: Some leaves also produce red pigments (anthocyanins) in the fall, which are responsible for the vibrant reds and purples we see. These pigments are produced as the leaf breaks down, and they may help protect the plant from damage by absorbing excess light energy.
