Explain how pigments absorb light in Photosynthesis

How Pigments absorb Light In Photosynthesis
 
Pigments are chemical compounds which reflect only certain wavelengths, flowers, corals, and even animal skin contain pigments which give them their colorsisible light. Because they interact with light to absorb only certain wavelengths, pigments are useful to plants and other autotrophs. Pigments are "molecules that absorb specific wavelengths (energies) of light and reflect all others."
There are three different types of Pigments;
 
-Chlorophylls are greenish pigments which contain a porphyrin ring.
-Carotenoids are usually red, orange, or yellow pigments, and include the familiar compound carotene, which gives carrots their color.
-Phycobilins are water-soluble pigments, and are therefore found in the cytoplasm, or in the stroma of the chloroplast.
