Glucose is a chemical molecule belonging to the group of carbohydrates, it is a simple sugar. Glucose is the basic unit used as fuel by a complex cellular enzymatic system that degrades this molecule to obtain energy for all the functions of the body of animals and plants. Glucose also participates as a precursor to other important substances.
Glucose is produced by plants through a process called photosynthesis, where glucose molecules are formed by joining water and carbon dioxide molecules with the help of solar energy and oxygen release. Glucose in plants serves as energy, reserves of nutrients (sucrose and starch, among other carbohydrates that are accumulated in fruits, seeds, stems, leaves and roots; each plant has its own way of making its reserve) and for its own formation and plant growth (all parts are made from the union of glucose molecules forming the cellulose that gives plants structures).
