    15979   Photosynthesis  The Synthesis by Organisms of Organic Chemical Compounds Especially Carbohydrates From Carbon Dioxide (co2) Using Energy Obtained From Light Rather Than From the Oxidation of Chemical Compounds. 
    18298   Protein Chromophore Linkage  The Covalent or Noncovalent Attachment of a Chromophore to a Protein. 
    55114   Oxidation Reduction Process  A Metabolic Process That Results in the Removal or Addition of One or More Electrons to or From a Substance with or Without the Concomitant Removal or Addition of a Proton or Protons. 
    9507   Chloroplast  A Chlorophyll Containing Plastid with Thylakoids Organized Into Grana and Frets or Stroma Thylakoids and Embedded in a Stroma. 
    9536   Plastid  Any Member of a Family of Organelles Found in the Cytoplasm of Plants and Some Protists Which Are Membrane Bounded and Contain Dna. Plant Plastids Develop From a Common Type the Proplastid. 
    9579   Thylakoid  A Membranous Cellular Structure That Bears the Photosynthetic Pigments in Plants Algae and Cyanobacteria. in Cyanobacteria Thylakoids Are of Various Shapes and Are Attached to or Continuous with the Plasma Membrane. in Eukaryotes They Are Flattened Membrane Bounded Disk Like Structures Located in the Chloroplasts; in the Chloroplasts of Higher Plants the Thylakoids Form Dense Stacks Called Grana. Isolated Thylakoid Preparations Can Carry Out Photosynthetic Electron Transport and the Associated Phosphorylation.
