What are the three major classes of photsynthetically active pigments?

Answer 1

Chlorophyll (A[green] and B[red] {c and d also exist}), caratonoids[orange] phycobiliproteins check the link in sources.

Answer 2

The color pigments in the leaves of plants, chlorophylls, carotenoids, and anthocyanins are not all involved in photosynthesis.
Chlorophylls are the primary photosynthetic pigment. They reflect green and absorb blue more than red wavelengths. Chlorophyll a, Chlorophyll b, Chlorophyll c1, Chlorophyll c2, & Chlorophyll d do the electron capture to process into carbohydrates for long term storage of energy.
Carotenoids reflect yellow, orange, or red and absorb blue light. There are over 600 known and they pass their energy to the chlorophyll so they are the second photosynthetic pigment.
Xanthophylls are a fourth common but sub class of the carotenoid group. They are photoprotective primarily Not directly photosynthetic.
Anthocyanins, a fifth and also minor pigment class, reflect red, blue, purple, or magenta colors. Recent literature reports some 550 but these are NOT involved in photosynthesis. They give color to flowers & fruit and are there for protection from UV or oxydative damage.

The third major photosynthetic pigment class, Phycobilins, are soluble in water & are not found in leaves. They occur in Cyanobacteria and Rhodophyta's photosynthesis pathway.

Answer 3

ok
Chlorophyll A
Chlorophyll B
and Cartorenoids,,,
the third one is spelt incorrectly my bio is a lil rusty but thats them right there..
good luck
n u should use your text book,, it give u alot more detail about them..
