Plants need water to survive, but many other factors can affect their growth including temperature, soil quality and nutrients.
Vitamin C — an important antioxidant for humans — also has useful functions in plants. Unlike humans, plants can create their own vitamin C and it plays a role in their growth and development, as well as dealing with environmental stress. Ibuprofen — a medication used as a pain reliever — can enter the waterways through sewage systems and eventually be absorbed by plants. This experiment examines the effect of these two compounds on the growth of plants.
