process these elements are digested and turned into organic matter, which are then sent to the stem above the ground, while any excess is stored in the roots. At the same time, green plants and leaves have a material called chlorophyll. The carbon-dioxide that is taken from the air through the air passages of green plants and leaves, along with the water that is carried through the roots are brought together by the chlorophyll and the sun, resulting in photosynthesis, which produces glucose, oxygen and water. The water and oxygen are expelled, while the glucose combines with other elements, creating carbohydrates.
