Setting a value for any of the cell or organelle attributes will make its diagram visible; Any number and combination of diagram attributes may be set; When multiple diagrams are activated, the title is suppressed {
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 ...

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.
There are numerous types of organelles with a wide variety of functions, including the various compartments of the endomembrane system (e.g. the nuclear envelope, endoplasmic reticulum, and Golgi apparatus), mitochondria, chloroplasts, lysosomes, endosomes, and vacuoles, among others. Many organelles are unique to particular cell types or species.
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 ...
In single-celled organisms such as members of the eukaryotes, the functional analogue of an organ is known as an organelle. In plants, there are three main organs. [3] The number of organs in any organism depends on the definition used. There are approximately 79 organs in the human body; the precise count is debated. [4]
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 .
