PIGMENTS
Pigments: absorb lightEX: a red object absorbs all
the visible colors of the spectrum except red which is reflected and gives the object the red color

Types of Photosynthetic Pigments
a. Chlorophyll: absorbs red and blue light, appear green
b. Carotenes: absorb blue,appear orange
c. Xanthophylls: appear yellow, may not be used to absorb light
