Carbon, Hydrogen and Oxygen make up about 90% of the dry matter in a plant. CO2 (Carbon Dioxide) in the air supplies all of the Carbon in the plant. Like animals, plants breathe in Oxygen and breathe out Carbon Dioxide all the time. The plant needs Carbon Dioxide during the hours of daylight and uses this to produce sugars. During the hours of darkness it will breathe out Carbon Dioxide, which is a waste product.

The plant uses light and Carbon Dioxide for photosynthesis. The more light there is available the greater the plant
