Question

A plant has a unique photosynthetic pigment. the leaves of this plant appear to be reddish yellow. what wavelengths of visible light are being absorbed by this pigment?

Answer 1

The wavelengths of visible light that are being absorbed by this pigment are red and yellow. A photosynthetic pigment or accessory pigment is a pigment that is present in chloroplasts or photosynthetic bacteria and captures the light energy necessary for photosynthesis. Photosynthesis in plants is dependent upon capturing light energy in the pigment chlorophyll, and in particular chlorophyll a. This chlorophyll resides mostly in the chloroplasts and gives leaves their green color.

Answer 2

Blue and Violet

Photosynthesis involves the process in which plants manufacture food by converting light energy into chemical energy in the presence of compounds such as water, carbon dioxide,sunlight etc.

Different Colors each have their different wavelengths. When light from a particular region of the spectrum are absorbed by a material which in this case is the reddish yellow pigment then the materials will appear to be the complementary color.

An example is the reddish yellow pigment which appear to be reddish yellow which is absorbed by blue and violet according to the absorption spectra attached.
