The Analysis of Spinach Pigmentation
During Photosynthesis
University of Alabama
I. Introduction:
"Photosynthesis is the conversion of light energy to chemical energy that is stored in glucose or other organic compounds; it occurs in plants, algae, and certain prokaryotes" (Campbell, G-16). The formula below is photosynthesis and "the ingredients necessary to make a plant grow" (KoK, 30).
6CO_2 + 6H_2_0,,³ C_6_H_12_O_6_ + 6CO_2
Photosynthesis occurs within chloroplasts which are in leaf cells. It takes carbon dioxide and water "within the chloroplast, sunlight powers the conversion of these ingredients to a sugar called glucose and oxygen" (Campbell, 37).
Pigments are substance that absorbs visible light. It depends on pigment of which wavelength of light is absorbed. The wavelength that reflects makes them appear to be colorful. Pigments are useful to plants because of the interaction with light to absorb certain wavelengths.
