Photosynthesis

Plants have a capacity that we humans can only imagine— the ability to produce food from sunlight. Sure, we can prepare some dishes that we can savor on, but it become possible because of the plants (as they serve as a producers of all the raw materials required). Photosynthesis is the method of assembling carbohydrates with the aid of sunlight.
