  1. Organelle

    In cell biology, an organelle is a specialized subunit within a cell that has a specific function, and it is usually separately enclosed within its own lipid bilayer. The name organelle comes from the idea that these structures are to cells what an organ is to the body. Organelles are identified by microscopy, and can also be purified by cell fractionation. There are many types of organelles, particularly in eukaryotic cells. While Prokaryotes do not possess organelles per se, some do contain protein-based microcompartments, which are thought to act as primitive organelles.
