Biology 101 chapter 6 notes (cid:862)a tour of the cell(cid:863) Concept 6. 1: biologists use microscopes and the tools of biochemistry to study cells, cells are usually too small to be seen by the naked eye. Microscopy: microscopes are used to visualize cells. 3d tissues and cells: techniques for labeling cells improves resolution. Cell fractionation: cell fractionation takes cells apart and separates the major organelles from one another, completed using a centrifuge, enables scientists to determine the functions of organelles, biochemistry and cytology correlate cell function with structure. Concept 6. 2: eukaryotic cells have internal membranes that compartmentalize their functions, the basic structural and functional unit of every organism is either prokaryotic or. Eukaryotic: prokaryotic: bacteria and archaea, eukaryotic: protists, fungi, animals, plants. A panoramic view of the eukaryotic cell: a eukaryotic cell has internal membranes that partition. The cell into organelles: the basic fabric of biological membranes is a double.
