Bioscience:Photosynthesis and Cellular Respiration
Photosynthesis uses light energy to make molecules that fuel the process of life. During photosynthesis， broad materials carbon dioxide and water are converted into energy-rich fuel molecules such as sugars and fatty acids. Only by certain ways can link of life drive photosynthesis. Chlorophyll molecules absorb light from red and blue regions of spectrum. When light hits the chlorophyll molecule， its energy raises one of the chlorophyll electrons to a higher energy level.
