  2. Photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Photosynthesis

    Photosynthesis usually refers to oxygenic photosynthesis, a process that produces oxygen. Photosynthetic organisms store the chemical energy so produced within intracellular organic compounds (compounds containing carbon) like sugars, glycogen , cellulose and starches .

  3. Biological pigment - Wikipedia

    en.wikipedia.org/wiki/Biological_pigment

    The various colors are made by the combination of the different layers of the chromatophores. These cells are usually located beneath the skin or scale the animals. There are two categories of colors generated by the cell – biochromes and schematochromes. Biochromes are colors chemically formed microscopic, natural pigments.

  4. Chlorophyll - Wikipedia

    en.wikipedia.org/wiki/Chlorophyll

    The most widely distributed form in terrestrial plants is chlorophyll a. The only difference between chlorophyll a and chlorophyll b is that the former has a methyl group where the latter has a formyl group. This difference causes a considerable difference in the absorption spectrum, allowing plants to absorb a greater portion of visible light.

  5. Chlorosis - Wikipedia

    en.wikipedia.org/wiki/Chlorosis

    An albino corn plant with no chlorophyll (left) beside a normal plant (right) In botany, chlorosis is a condition in which leaves produce insufficient chlorophyll.As chlorophyll is responsible for the green color of leaves, chlorotic leaves are pale, yellow, or yellow-white.

  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. Evolution of photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Evolution_of_photosynthesis

    C 3 photosynthesis is the oldest and most common form. A C3 plant uses the Calvin cycle for the initial steps that incorporate CO 2 into organic material. A C4 plant prefaces the Calvin cycle with reactions that incorporate CO 2 into four-carbon compounds. A CAM plant uses crassulacean acid metabolism, an adaptation for photosynthesis in arid ...

  8. Leaf - Wikipedia

    en.wikipedia.org/wiki/Leaf

    A leaf (pl.: leaves) is a principal appendage of the stem of a vascular plant, [1] usually borne laterally above ground and specialized for photosynthesis.Leaves are collectively called foliage, as in "autumn foliage", [2] [3] while the leaves, stem, flower, and fruit collectively form the shoot system. [4]

  9. Chloroplast - Wikipedia

    en.wikipedia.org/wiki/Chloroplast

    The carbon fixed through photosynthesis is stored in the form of paramylon, which is contained in membrane-bound granules in the cytoplasm of the euglenophyte. [12] [32] Chlorarachnion reptans is a chlorarachniophyte. Chlorarachniophytes replaced their original red algal endosymbiont with a green alga.
