Home News Research News Chlorophyll. The true color of chlorophyll The light harvesters in plant photosynthesis are bluer than we think. April 05, Dept Theory. In a recent publication in the journal Angewandte Chemie International Edition , a group of researchers including Angel Rubio, director of the theory department of the Max Planck Institute for the Structure and Dynamics of Matter, developed a method that allows measuring the color of chlorophyll pigments outside of their cell environment.
This work might pave the way to a better understanding of photosynthesis, potentially leading to the development of more efficient photovoltaic devices. Other Interesting Articles.

All photosynthetic organisms have chlorophyll a which absorbs violet-blue and reddish orange-red wavelengths. Chlorophyll a reflects green and yellow-green wavelengths. Accessory photosynthetic pigments, including chlorophyll b and beta-carotene, absorb energy that chlorophyll a does not absorb.
Chlorophyll only triggers a chemical reaction when it is associated with proteins embedded in a membrane, such as in thylakoid membranes of the chloroplast or membrane infoldings found in photosynthetic prokaryotes. Which color of light does chlorophyll absorb more of than any other color? Biology Energy In Organisms Photosynthesis. Suren Abreu. Nov 1, Chlorophyll absorbs light of the red and blue wavelengths more.
Carotenoids are another key group of pigments that absorb violet and blue-green light see spectrum graph above. In conclusion, plant leaves are green because green light is less efficiently absorbed by chlorophylls a and b than red or blue light, and therefore green light has a higher probability to become diffusely reflected from cell walls than red or blue light.
As such, plants look green because they absorb red light most efficiently and the green light is reflected. If they absorbed more, they would look black to our eyes. Plants are green because the small amount of light they reflect is that color. For a plant, the pigment chlorophyll absorbs blue and red light and reflects green light as you mentioned.
Chlorophyll is the main pigment used by plants to use light to make sugars through photosynthesis. Photosynthesis is the process by which plants convert energy from the sun. It is the process that allows plants to create organic molecules that they use as fuel. Here is how it works. The molecules of chlorophyll contained in the chloroplasts absorb energy in the form of light from the sun. What would happen to photosynthesis if the green light waves that reach a plant were blocked?
