Plants need photosynthesis in the same way that you need to eat. They convert the energy of the sun into glucose using water and carbon dioxide. They release oxygen, which you need like they need carbon dioxide. They use the glucose to grow. When we eat plants, we eat them for the glucose because we convert glucose into ATP, which is the energy molecule. We use ATP constantly to function, which is why we have to regularly consume food. That's why you eat your green vegetables. Plants that use photosynthesis are green because they absorb every color of light from the sun except for green, which they reflect because green light isn't efficient.

Yeah, whut he said.
