Chemical Properties Of Plants

The Chemical Composition of Plants

· Since plants require nutrients in the form of elements such as carbon and potassium it is important to understand the chemical composition of plants The majority of volume in a plant cell is water it typically comprises 80 to 90 percent of the plant s total weight Soil is the water source for land plants It can be an abundant source of water even if it appears dry Plant roots absorb

Plants That Have Antimicrobial Properties
