Chlorophylls and their absorption spectrum
The maximum absorption of the two most common chlorophylls is 430 and 662nm for chlorophyll a and 453 and 642nm for chlorophyll b.
Chlorophylls are a group of organic chemical compounds present, among others, in in plants. In photosynthetic organisms, they catch light quanta and transfer energy to the reaction center of the photosystem. They are responsible for the green color of plants. This is due to the high absorption in the red and blue parts of the light spectrum and low absorption in the green part of the spectrum.
The most common chlorophylls in nature are chlorophyll a and chlorophyll b. They are found in all photosynthetic plants.
The quantitative ratios of chlorophylls in plants depend, inter alia, on the habitat conditions: shade-loving (shade-tolerant) plants have more chlorophyll b, light-loving (light-loving) plants – chlorophyll a.
An example of color perception.
The banana does not emit yellow light. Banana peel absorbs all light waves of frequency except light from certain frequency ranges together perceived by us as yellow.
