Chlorophyll is a pigment found in plants that gives them their green color and helps them make their own food. Photosynthesis uses the energy from the sun and stores this energy in the bonds of glucose. Chlorophyll is the name given to a group of green pigment molecules found in plants, algae, and cyanobacteria. The level of liquid in the volumeter went up because the plant was producing oxygen during photosynthesis.
