Answer

Plant pigments capture light from the sun for cells of the plant to use during the process of photosynthesis.

Work Step by Step

Plant pigments include chlorophyll and other pigments such as carotene. Chlorophyll reflects green light but absorbs light that is blue-violet or red, which is the reason why chlorophyll makes plants appear green. Carotene, on the other hand, reflects red and orange light and absorbs light in other regions of the visible spectrum. The capturing of sunlight by these pigments is essential to the process of photosynthesis.
