  2. Erythropoiesis - Wikipedia

    en.wikipedia.org/wiki/Erythropoiesis

    Erythropoiesis (from Greek 'erythro' meaning "red" and 'poiesis' "to make") is the process which produces red blood cells (erythrocytes), which is the development from erythropoietic stem cell to mature red blood cell. [1] It is stimulated by decreased O 2 in circulation, which is detected by the kidneys, which then secrete the hormone ...

  3. Genetic transformation - Wikipedia

    en.wikipedia.org/wiki/Genetic_transformation

    Plant tissue (often leaves) are cut into small pieces, e.g. 10x10mm, and soaked for ten minutes in a fluid containing suspended Agrobacterium. The bacteria will attach to many of the plant cells exposed by the cut. The plant cells secrete wound-related phenolic compounds which in turn act to upregulate the virulence operon of the Agrobacterium.

  4. Photophosphorylation - Wikipedia

    en.wikipedia.org/wiki/Photophosphorylation

    In the process of photosynthesis, the phosphorylation of ADP to form ATP using the energy of sunlight is called photophosphorylation. Cyclic photophosphorylation occurs in both aerobic and anaerobic conditions, driven by the main primary source of energy available to living organisms, which is sunlight.

  5. Genetic engineering techniques - Wikipedia

    en.wikipedia.org/wiki/Genetic_engineering_techniques

    The bacteria will attach to many of the plant cells exposed by the cuts. The bacteria uses conjugation to transfer a DNA segment called T-DNA from its plasmid into the plant. The transferred DNA is piloted to the plant cell nucleus and integrated into the host plants genomic DNA.The plasmid T-DNA is integrated semi-randomly into the genome of ...

  6. Evolution of photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Evolution_of_photosynthesis

    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 conditions. C4 and CAM plants have special adaptations ...

  7. Plant tissue culture - Wikipedia

    en.wikipedia.org/wiki/Plant_tissue_culture

    Plant tissue culture is a collection of techniques used to maintain or grow plant cells, tissues, or organs under sterile conditions on a nutrient culture medium of known composition. It is widely used to produce clones of a plant in a method known as micropropagation .

  8. Photosystem I - Wikipedia

    en.wikipedia.org/wiki/Photosystem_I

    Photosystem I (PSI, or plastocyanin–ferredoxin oxidoreductase) is one of two photosystems in the photosynthetic light reactions of algae, plants, and cyanobacteria. Photosystem I [1] is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from plastocyanin to ferredoxin.

  9. Photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Photosynthesis

    Although there are some differences between oxygenic photosynthesis in plants, algae, and cyanobacteria, the overall process is quite similar in these organisms. There are also many varieties of anoxygenic photosynthesis , used mostly by bacteria, which consume carbon dioxide but do not release oxygen.
