Carotenoids are important to many plants because these pigments are able to
A)remove carbon dioxide from the air.
B)absorb wavelengths of light that neither chlorophyll a nor b can absorB.
C)absorb water so that hydrolysis can be carried out in the chloroplasts.
D)capture UV radiation that is harmful to the DNA in the nucleus of plant cells.
E)store electrons for use during the "dark" reaction of photosynthesis.

Question

Quizplus · Accepted Answer

Carotenoids are pigments that are able to absorb wavelengths of light that are not efficiently absorbed by chlorophyll a and b. This expands the range of light that can be used for photosynthesis, and allows the plant to harvest more energy from the sun. Carotenoids also play a role in protecting the plant from photo-damage caused by excess light or UV radiation. They do not remove carbon dioxide from the air, absorb water, store electrons, or capture UV radiation that is harmful to the DNA in the nucleus of plant cells.
