Cellular level Carbon, hydrogen, and phosphate coming together to form the phospholipids of a cellular membrane. Chemical level Using this definition, there would only be two broad classes of organelles (i.e. those that contain their own DNA, and have originated from endosymbiotic bacteria ): mitochondria (in almost all eukaryotes) plastids [18] (e.g. in plants, algae, and some protists). Zobacz więcej In cell biology, an organelle is a specialized subunit, usually within a cell, that has a specific function. The name organelle comes from the idea that these structures are parts of cells, as organs are to the body, hence … Zobacz więcej In biology organs are defined as confined functional units within an organism. The analogy of bodily organs to microscopic cellular substructures is obvious, as from even early … Zobacz więcej Eukaryotic cells are structurally complex, and by definition are organized, in part, by interior compartments that are themselves enclosed by lipid membranes that resemble the … Zobacz więcej • CoRR hypothesis • Ejectosome • Endosymbiotic theory Zobacz więcej While most cell biologists consider the term organelle to be synonymous with cell compartment, a space often bound by one or two lipid … Zobacz więcej Prokaryotes are not as structurally complex as eukaryotes, and were once thought as having little internal organization, and lack cellular compartments and internal membranes; … Zobacz więcej
