In summary, chlorine dioxide at
Photosynthesis: How do plants get energy?
labsci.stanford.eduCreated by LABScI at Stanford 2 Key Concepts: • Photosynthesis is the primary means by which plants get their energy. They derive this energy from a sugar called glucose (C 6 H 12 O 6). • To make glucose, sunlight is captured in pigments like chlorophyll, the substance that gives leaves their green color.
