  • Chlorophylls absorb light most strongly in the red and violet portions of the spectrum. Green light is poorly absorbed so when white light (which contains the entire visible spectrum) shines on leaves, green rays are transmitted and reflected giving leaves their green color. The similarity of the action spectrum of photosynthesis and the absorption spectrum of chlorophyll tells us that chlorophylls are the most important pigments in the process.

Chlorophyll absorbs:

Red light wavelength 650 nm

some Orange light 590 nm

some Yellow light 570 nm

Blue light 475 nm

Indigo light 445 nm

Violet light 400 nm

It reflects green light 510 nm.

[The spectral region where the least light is absorbed is between , between 500-600nm.]

An absorption spectrum is a spectrum of radiant energy whose intensity at each wavelength is a measure of the amount of energy at that wavelength that has passed through a selectively absorbing substance, here chlorophyll.

Note that both chlorophylls absorb light most strongly in the red and violet portions of the spectrum. Green light is poorly absorbed so when white light (which contains the entire visible spectrum) shines on leaves, green rays are transmitted and reflected giving leaves their green color.

When using the electromagnetic spectrum, Chlorophyll is shown to absorb light most strongly in the blue portion of the spectrum. After blue, red would be the next strongest with green and near green portions its weakest. This explains the green color of Chlorophyll tissues.

Chlorophyll absorbs all colors except for green (green is reflected and therefore visible).

Also, chlorophyll in photosystem II, or p680 absorbs predominantly red light, and chlorophyll in photosystem I, known as p700 absorbs blue light the best. But as stated above, both reflect green light giving photosynthetic plants their green color.

The absorption spectrum in chlorophyll is a chart of what colors of light a plant absorbs the most of. In most cases, the plant absorbs a lot of red and blue, but reflects green.

What is the relation between the electromagnetic spectrum of solar radiation and the absorption spectrum of chlorophyll?

Solar radiation peaks in energy in the mid-yellow range. Chlorphyll's absorption also peaks in this range. It is a demonstration of the adaption of plants to optimizing their production efficiency.

What is the photosynthetic pigment in plants?

There are a four main photosynthetic pigments in green plants. Chlorophyll a, chlorophyll b, carotene and xanthophyll. These all absorb different areas of the spectrum therefore allowing the plant maximum absorption of light from the sun, and hence photosynthesise effectively.
