Chlorophyll is green because

• it absorbs green wavelengths
• it reflects green wavelengths of light
• of an optical illusion caused by transmitted light
• it absorbs blue and yellow wavelengths, which makes green

Light energy is converted to chemical energy through the process of 

• photosynthesis
• glycolysis
• cellular respiration
• fermentation
