Experiments on the absorption spectra of chlorophyll and carotenoids

Summary

Because chlorophyll and carotenoids have different molecular structures, they have different absorption spectra. Carotenoids absorb blue-violet light and chlorophyll absorbs red and blue-violet light.

Operation method

Experiments on the absorption spectra of chlorophyll and carotenoids

Principle

Because chlorophyll and carotenoids have different molecular structures, they have different absorption spectra. Carotenoids absorb blue-violet light and chlorophyll absorbs red and blue-violet light.

Materials and Instruments

Chlorophyll Carotenoids Spectroscopy Light Source Colored Pencil

Move

The spectroscope was first adjusted so that the continuous spectrum of the light source could be clearly observed, and then the absorption spectra of the chlorophyll and carotenoid extracts were observed separately.

Represent the results obtained from the observations in a colored pencil drawing and explain how the absorption regions of the spectrum differ for these two types of pigments.
