  2. Chlorophyll - Wikipedia

    en.wikipedia.org/wiki/Chlorophyll

    Synthetic chlorophyll is registered as a food additive colorant, and its E number is E140. Chefs use chlorophyll to color a variety of foods and beverages green, such as pasta and spirits. Absinthe gains its green color naturally from the chlorophyll introduced through the large variety of herbs used in its production. [46]

  3. Chromophore - Wikipedia

    en.wikipedia.org/wiki/Chromophore

    Leaves change color in the fall because their chromophores (chlorophyll molecules) break down and stop absorbing red and blue light. [1] A chromophore is a molecule which absorbs light at a particular wavelength and reflects color as a result. Chromophores are commonly referred to as colored molecules for this reason.

  4. Chlorophyll a - Wikipedia

    en.wikipedia.org/wiki/Chlorophyll_a

    Chlorophyll does not reflect light but chlorophyll-containing tissues appear green because green light is diffusively reflected by structures like cell walls. [4] This photosynthetic pigment is essential for photosynthesis in eukaryotes, cyanobacteria and prochlorophytes because of its role as primary electron donor in the electron transport ...

  5. Biological pigment - Wikipedia

    en.wikipedia.org/wiki/Biological_pigment

    Biochromes are colors chemically formed microscopic, natural pigments. Their chemical composition is created to take in some color of light and reflect the rest. In contrast, schematochromes (structural colors) are colors created by light reflections from a colorless surface and refractions by tissues.

  6. Chlorophyll b - Wikipedia

    en.wikipedia.org/wiki/Chlorophyll_b

    Chlorophyll b is a form of chlorophyll. Chlorophyll b helps in photosynthesis by absorbing light energy. It is more soluble than chlorophyll a in polar solvents because of its carbonyl group. Its color is green, and it primarily absorbs blue light. [2] In land plants, the light-harvesting antennae around photosystem II contain the majority of ...

  7. Phycocyanin - Wikipedia

    en.wikipedia.org/wiki/Phycocyanin

    It is an accessory pigment to chlorophyll. All phycobiliproteins are water-soluble, so they cannot exist within the membrane like carotenoids can. Instead, phycobiliproteins aggregate to form clusters that adhere to the membrane called phycobilisomes. Phycocyanin is a characteristic light blue color, absorbing orange and red light, particularly ...

  8. Photosynthetic pigment - Wikipedia

    en.wikipedia.org/wiki/Photosynthetic_pigment

    Chlorophyll a is the most common of the six, present in every plant that performs photosynthesis. Each pigment absorbs light more efficiently in a different part of the electromagnetic spectrum. Chlorophyll a absorbs well in the ranges of 400–450 nm and at 650–700 nm; chlorophyll b at 450–500 nm and at 600–650 nm. Xanthophyll absorbs ...

  9. Talk:Chlorophyll - Wikipedia

    en.wikipedia.org/wiki/Talk:Chlorophyll

    Chlorophylls do not reflect light." This is one of several contradictions. If green light is not or less efficiently absorbed in chlorophyll, that just means that chlorophyll reflects part of the green light. If this green light is scattered by cell structures, doesn't mean that chlorophyll does not reflect light.
