  2. Organelle - Wikipedia

    en.wikipedia.org/wiki/Organelle

    Organelle. In cell biology, an organelle is a specialized subunit, usually within a cell, that has a specific function. The name organelle comes from the idea that these structures are parts of cells, as organs are to the body, hence organelle, the suffix -elle being a diminutive. Organelles are either separately enclosed within their own lipid ...

  3. Cell membrane - Wikipedia

    en.wikipedia.org/wiki/Cell_membrane

    The content of the cell, inside the cell membrane, is composed of numerous membrane-bound organelles, which contribute to the overall function of the cell. The origin, structure, and function of each organelle leads to a large variation in the cell composition due to the individual uniqueness associated with each organelle.

  4. Cell (biology) - Wikipedia

    en.wikipedia.org/wiki/Cell_(biology)

    The cell is the basic structural and functional unit of all forms of life. Every cell consists of cytoplasm enclosed within a membrane; many cells contain organelles, each with a specific function. The term comes from the Latin word cellula meaning 'small room'. Most cells are only visible under a microscope.

  5. Cell nucleus - Wikipedia

    en.wikipedia.org/wiki/Cell_nucleus

    Lysosome. Centrosome. Cell membrane. The cell nucleus (from Latin nucleus or nuculeus 'kernel, seed'; pl.: nuclei) is a membrane-bound organelle found in eukaryotic cells. Eukaryotic cells usually have a single nucleus, but a few cell types, such as mammalian red blood cells, have no nuclei, and a few others including osteoclasts have many.

  6. Centrosome - Wikipedia

    en.wikipedia.org/wiki/Centrosome

    In cell biology, the centrosome (Latin centrum 'center' + Greek sōma 'body') (archaically cytocentre [1]) is an organelle that serves as the main microtubule organizing center (MTOC) of the animal cell, as well as a regulator of cell-cycle progression. The centrosome provides structure for the cell. The centrosome is thought to have evolved ...

  7. Golgi apparatus - Wikipedia

    en.wikipedia.org/wiki/Golgi_apparatus

    Centrosome. Cell membrane. The Golgi apparatus (/ ˈɡɒldʒi /), also known as the Golgi complex, Golgi body, or simply the Golgi, is an organelle found in most eukaryotic cells. [ 1 ] Part of the endomembrane system in the cytoplasm, it packages proteins into membrane-bound vesicles inside the cell before the vesicles are sent to their ...

  8. Vacuole - Wikipedia

    en.wikipedia.org/wiki/Vacuole

    Plant cell structure. Animal cell structure. A vacuole (/ ˈvækjuːoʊl /) is a membrane-bound organelle which is present in plant and fungal cells and some protist, animal, and bacterial cells. [1][2] Vacuoles are essentially enclosed compartments which are filled with water containing inorganic and organic molecules including enzymes in ...

  9. Cilium - Wikipedia

    en.wikipedia.org/wiki/Cilium

    67181. Anatomical terms of microanatomy. [edit on Wikidata] Look up cilium in Wiktionary, the free dictionary. The cilium (pl.: cilia; from Latin cilium ' eyelid '; in Medieval Latin and in anatomy, cilium is an eyelash) is a membrane -bound organelle found on most types of eukaryotic cell. [1] (. Cilia are absent in bacteria and archaea.)
