Chlorophyll a

Definition

noun

A type of chlorophyll that is most common and predominant in all oxygen-evolving photosynthetic organisms such as higher plants, red and green algae. It is best at absorbing wavelength in the 400-450 nm and 650-700 nm of the electromagnetic spectrum. Its molecular formula is C55H72O5N4Mg.


Supplement

There are different forms of chlorophylls existing in nature. Some of them are:

They all reflect the green light but the slight differences in their structure cause them to appear in different shades of green. For instance, chlorophyll a is a blue-green pigment.
