CO2 | Noun
- Carbon dioxide (CO2) is a natural gas exhaled by animals and plants, and absorbed by plants during the process of photosynthesis. In photosynthesis, carbon dioxide and water is converted into sugar, stimulating plant growth. Trees and flowers also bloom thanks to the absorption of carbon dioxide. Additionally, plants convert carbon dioxide into oxygen via photosynthesis, consequently providing oxygen for animals. Carbon dioxide is absorbed through a plant’s leaves and diffused through a plant’s stomata, that are holes located on the underside of a leaf.
