what is an organelle bio
In cell biology, an organelle /ÉrÉ¡ÉËnÉl/ is a specialized subunit within a cell that has a specific function.Individual organelles are usually separately enclosed within their own lipid bilayers.The name organelle comes from the idea that these structures are to cells what an organ is to the body (hence the name organelle, the suffix-elle being a diminutive).evertheless, the use of organelle to refer to non-membrane bound structures such as ribosomes is common. This has led some texts to delineate between membrane-bound and non-membrane bound organelles.
