Carbon Dioxide (CO2)

Last Updated: February 24, 2019

Definition - What does Carbon Dioxide (CO2) mean?

Carbon dioxide (CO2) is a natural gas exhaled by animals and plants, and absorbed by plants during the process of photosynthesis. Vital to life, carbon dioxide also occurs naturally in seawater, glaciers, ice caps, rivers, groundwater, and lakes.

Carbon dioxide is formed when oxygen and carbon atoms bond together, often via a combustion process inside animals and plants (cellular respiration), and machines that burn fossil fuels.

Carbon dioxide is crucial to plant growth. In algae and plants, this gas is converted into different types of organic molecules that are rich in energy, such as the sugar known as glucose.

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, which basically are holes located on the underside of a leaf. Thanks to the stomata, carbon dioxide is also transferred to the various cells located in the leaves.
