Immature dragonflies have six spindly legs, and a body that is only a few times longer than it is wide. They have two fairly big eyes. Some of their mouthparts are modified to shoot forward and grab prey.
An organelle is a tiny cellular structure that performs specific functions within a cell. Organelles are embedded within the cytoplasm of eukaryotic and prokaryotic cells. In the more complex eukaryotic cells, organelles are often enclosed by their own membrane. Analogous to the body's internal organs, organelles are specialized and perform valuable functions necessary for normal cellular operation.
In cell biology, an organelle /ÉrÉ¡ÉËnÉl/ 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.
