  2. Organelle - Wikipedia

    en.wikipedia.org/wiki/Organelle

    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 bilayers (also called membrane-bounded organelles) or are spatially distinct functional units without a surrounding ...

  3. Contractile vacuole - Wikipedia

    en.wikipedia.org/wiki/Contractile_vacuole

    The number of contractile vacuoles in each species is mostly constant and is therefore used for species characterization in systematics. The contractile vacuole has several structures attached to it in most cells, such as membrane folds, tubules, water tracts and small vesicles.

  4. Vacuole - Wikipedia

    en.wikipedia.org/wiki/Vacuole

    A vacuole (/ ˈ v æ k juː oʊ l /) 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 solution , though in certain cases ...

    en.wikipedia.org/wiki/Category:Organelles

    Organelles are small unique structures of a cell that perform specialized tasks. They are often suspended in the cytosol , or attached to the plasma membrane . Organelles were historically identified through the use of some form of microscopy and by cell fractionation .

  6. Cell biology - Wikipedia

    en.wikipedia.org/wiki/Cell_biology

    It anchors organelles within the cells and makes up the structure and stability of the cell. The cytoskeleton is composed of three principal types of protein filaments: actin filaments, intermediate filaments, and microtubules, which are held together and linked to subcellular organelles and the plasma membrane by a variety of accessory proteins.

  7. Centriole - Wikipedia

    en.wikipedia.org/wiki/Centriole

    3D rendering of centrioles showing the triplets. In cell biology a centriole is a cylindrical organelle composed mainly of a protein called tubulin. [1] Centrioles are found in most eukaryotic cells, but are not present in conifers (), flowering plants (angiosperms) and most fungi, and are only present in the male gametes of charophytes, bryophytes, seedless vascular plants, cycads, and Ginkgo.

  8. Talk:Organelle - Wikipedia

    en.wikipedia.org/wiki/Talk:Organelle

    Though, one suggestion could be the introduction between proteins and organelles, it could be interpreted as irrelevant to the article considering it introduces it in a couple of sentences. The statements could be best represented in the historical section of the article instead of its own section or expanded on its relation.

  9. Cellular compartment - Wikipedia

    en.wikipedia.org/wiki/Cellular_compartment

    In terms of protein synthesis, the necessary organelles are relatively near one another. The nucleolus within the nuclear envelope is the location of ribosome synthesis. The destination of synthesized ribosomes for protein translation is rough endoplasmic reticulum (rough ER), which is connected to and shares the same membrane with the nucleus.
