The Cell Energy Cycle Gizmo is a cool way to learn about two important processes in life. These processes are photosynthesis and cellular respiration, and both involve many complex steps. However, the basic reactants in each process are very simple – glucose, water, and oxygen.
Photosynthesis is a process that converts radiant energy from sunlight into chemical energy. This process takes place in a cell called a chloroplast. This molecule contains chlorophyll, a green pigment that converts sunlight into chemical energy. It is used by plants, animals, and fungi for energy.
