  2. Chlorophyll - Wikipedia

    en.wikipedia.org/wiki/Chlorophyll

    The most widely distributed form in terrestrial plants is chlorophyll a. Chlorophyll a has methyl group in place of a formyl group in chlorophyll b. This difference affects the absorption spectrum, allowing plants to absorb a greater portion of visible light. The structures of chlorophylls are summarized below: [18] [19]

  3. 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 ...

  4. Chloroplast - Wikipedia

    en.wikipedia.org/wiki/Chloroplast

    It is the chlorophylls a and b together that make most plant and green algal chloroplasts green. [150] Chlorophyll c is mainly found in secondary endosymbiotic chloroplasts that originated from a red alga, although it is not found in chloroplasts of red algae themselves. Chlorophyll c is also found in some green algae and cyanobacteria. [12]

  5. Photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Photosynthesis

    Plants absorb light primarily using the pigment chlorophyll. The green part of the light spectrum is not absorbed but is reflected, which is the reason that most plants have a green color. Besides chlorophyll, plants also use pigments such as carotenes and xanthophylls. [25]

  6. Chlorophyll a - Wikipedia

    en.wikipedia.org/wiki/Chlorophyll_a

    It absorbs most energy from wavelengths of violet-blue and orange-red light, and it is a poor absorber of green and near-green portions of the spectrum. [3] Chlorophyll does not reflect light but chlorophyll-containing tissues appear green because green light is diffusively reflected by structures like cell walls. [4]

  7. Biological pigment - Wikipedia

    en.wikipedia.org/wiki/Biological_pigment

    Chlorophyll is the primary pigment in plants; it is a chlorin that absorbs blue and red wavelengths of light while reflecting a majority of green. It is the presence and relative abundance of chlorophyll that gives plants their green color. All land plants and green algae possess two forms of this pigment: chlorophyll a and chlorophyll b.

  8. Light-harvesting complexes of green plants - Wikipedia

    en.wikipedia.org/wiki/Light-harvesting_complexes...

    The light-harvesting complex (or antenna complex; LH or LHC) is an array of protein and chlorophyll molecules embedded in the thylakoid membrane of plants and cyanobacteria, which transfer light energy to one chlorophyll a molecule at the reaction center of a photosystem. The antenna pigments are predominantly chlorophyll b, xanthophylls, and ...

  9. Photosynthetically active radiation - Wikipedia

    en.wikipedia.org/wiki/Photosynthetically_active...

    Chlorophyll, the most abundant plant pigment, is most efficient in capturing red and blue light. Accessory pigments such as carotenes and xanthophylls harvest some green light and pass it on to the photosynthetic process, but enough of the green wavelengths are reflected to give leaves their characteristic color.
