• Biological pigment Chromatophore Fluorophore Litmus Pharmacophore Photophore, glandular organ Pigment Spectroscopy Visual phototransduction Woodward's rules Kräutler, Bernhard (26 February 2016). (wikipedia.org)
  • Description of Phaeophyceae (Brown Algae): They are commonly known as brown algae, due to the presence of a golden brown xanthophyll pigment, fucoxanthin (C40H54O6) in the chromatophores. (andymatthewsphotography.com)
  • Out of these pigment fucoxanthin is brown pigment that masks the traditional green colour of chlorophyll. (andymatthewsphotography.com)
  • Species colour varies from dark brown to olive green, depending upon the proportion of brown pigment (fucoxanthin) to green pigment (chlorophyll). (andymatthewsphotography.com)
  • The colorful patterns on their skin are caused by pigment cells called chromatophores. (talkpainting.com)
  • The patterns are created when the chromatophores enlarge or contract, exposing more or less of the pigment cells. (talkpainting.com)
  • On the other hand, another well-known pigment, chlorophyll is a structurally rather different molecule that does a very similar job (although plants take things a step further, utilizing sunlight rather than just blocking it). (stackexchange.com)
  • The photosynthetic organelles are called chromatophores. (pw.live)
  • The term chromatophore can also refer to coloured, membrane-associated vesicles found in some forms of photosynthetic bacteria . (wikipedia.org)
  • The most conspicuous of cytoplasmic structures are the brownish plastids which contain chlorophyll-a and -c, beta-carotenes and a number of xanthophyll's including the fucoxanthin which masks the chloroplasts and is responsible for the characteristics color of the plant thallus. (botanystudies.com)
  • b) Brown algae have chlorophyll a and c and fucoxanthin. (recruitmenttopper.com)
  • They vary in shape (spherical, ovoid, or irregular) and contain a large chloroplast (with chlorophyll A and B which gives them their green appearance) with a folded membrane. (microscopemaster.com)
  • In these two examples, a metal is complexed at the center of a tetrapyrrole macrocycle ring: the metal being iron in the heme group (iron in a porphyrin ring) of hemoglobin, or magnesium complexed in a chlorin-type ring in the case of chlorophyll. (wikipedia.org)
  • The reactions that actually trap the metal ion in the "cage" are typically pretty well selective at putting iron in hemoglobin and magnesium in chlorophyll. (stackexchange.com)
  • The top portion, which usually comes in a shade of red, orange, yellow, or pink, becomes that color because it no longer produces chlorophyll, the stuff that turns plants green. (talkpainting.com)

  • Outside, the chlorella cell is covered with a membrane, under which there is a cytoplasm with a nucleus, and in the cytoplasm there is a green chromatophore. (newmedia1.net)
  • In plants, Magnesium is typically found at the center of this ring and that helps to make chlorophyll green. (stackexchange.com)
  • Reptiles like chameleons and anoles have specialized cells called chromatophores that allow them to change skin color for signaling and temperature regulation. (colorwithleo.com)
  • These types of chlorophyll and bacteriochlorophyll differ in structure, and those differences affect the specific wavelength of light that each can absorb, which allows several different species of microbes together to collect the full spectrum of light, each absorbing a different range of wavelengths. (dummies.com)
  • Within this structure (chromatophore) is the pyrenoid where carbon fixation occurs. (microscopemaster.com)
  • Contractions in the chromatophores alter the skin's structure, density, and reflected wavelengths to create patterns of color change. (colorwithleo.com)
  • Chromatophores in cephalapods, including squid, cuttlefish and octopus, are complex organs made up of both muscle and nerve and provide the ability for the animal to rapidly change its skin color in order to blend into the surrounding environment to avoid predation, communicate, or send a warning signal. (noaateacheratsea.blog)
  • The main role of chloroplasts is to conduct photosynthesis, where the photosynthetic pigment chlorophyll captures the energy from sunlight and converts it and stores it in the energy-storage molecules ATP and NADPH while freeing oxygen from water. (alchetron.com)
  • The term chromatophore can also refer to coloured, membrane-associated vesicles found in some forms of photosynthetic bacteria . (wikipedia.org)
  • blue and green sunlight become available for photosynthetic energy conversion through the light-harvesting (lh) function of carotenoids, which involves transfer of carotenoid singlet excited states to nearby (bacterio)chlorophylls (bchls). (liverpool.ac.uk)
  • we have discovered that all carotenoids are surrounded either by aromatic residues or by chlorophylls in all known crystal structures of the photosynthetic pigment-protein complexes. (liverpool.ac.uk)
  • On the thylakoid membranes are photosynthetic pigments, including chlorophyll a . (alchetron.com)
  • A major hypothesis guiding the work is that a "horizontal" pathway for communication between chromatophores exists in the plane of the skin, and that this network can mediate chromogenic behaviors in the absence of descending motor control by the central nervous system. (stanford.edu)
