Why are most plans green?
Plants look green to us because they absorb red light most efficiently and reflect green light. Red light is absorbed by chlorophyll molecules in plants which use it for photosynthesis. Photosynthesis is the process by which plants and other organisms use sunlight to synthesize foods from carbon dioxide and water.
Below is an instruction that describes a task, paired with an input that provides further context. Write a response that appropriately completes the request.
