Why are plants green?
The short answer is because all plants contain chlorophyll, and chlorophyll reflects green light. Sunlight contains all the colors of the rainbow, including green. But green is the one color that chlorophyll can't absorb, so green is reflected back.
Chlorophyll is used in photosynthesis, the process that plants use to convert carbon dioxide into glucose (sugar), using energy from the sun.
