Light is absorbed,reflected and transmitted by a leaf.

The photosynthetic pigments from a leaf can be separated by chromatography.

Chlorophyll absorbs light primarily in the blue and red regions of the spectrum of white light.
Accessory pigments, such as xanthophyll and carotene absorb blue-green light.

The quantity of light absorbed by a pigment at different wavelengths of light can be represented as a graph called an absorption spectrum; the rate of photosynthesis that occurs in a plant at different wavelengths of light can…
