Medicinal plants have been used for a long time by our ancestors and are known to have an important role in the cure and treatment of some diseases. In some communities, these plants symbolize the only way of treating certain pathologies. It is estimated that approximately 80% of the planet's population has already used some vegetable to relieve symptoms of some disease.
However, there are medicinal plants that are unknown to science, which concerns not only scientists, but also health professionals in general. This is because these plants would provide the advance of medical sciences in a cheap and fast way, besides being able to help many sick people. However, none of this will happen if these plants remain unknown.
The reasoning behind this is because these unidentified plants could be used to cure diseases, used for food, and many scientists may even use these plants to create cosmetics. I really hope this helps and I just thought this off the top of my head so its may not be 100% accurate but its the basics of it.
The reactions of the Calvin cycle add carbon (from carbon dioxide in the atmosphere) to a simple five-carbon molecule called RuBP. These reactions use chemical energy from NADPH and ATP that were produced in the light reactions. The final product of the Calvin cycle is glucose.
