Document Summary

Nosepiece rotates to place lenses in position. Stage foundation for slide with hole for light to come through. Fine adjustment knob makes fine adjustments to focus use at high powers. Coarse adjustment knob makes big adjustments to focus use at low powers. Carry upright with one hand on arm & one hand under base. Begin focus on lowest power only coarse adjust knob at this power. Use a coverslip on temporary/wet mount slides. Never remove any parts of the microscope. Magnification power of an instrument to visually enlarge. Total magnification ocular magnification x objective magnification. Resolution ability to distinguish two objects as separate. Cell: know structure & function of each part fig 3. 1, table 3. 1. Plasma membrane phospholipid bilayer, transmembrane protein peripheral protein, channel protein, cholesterol. Fxn: defines boundary of cell, governs interactions with other cells and controls passage of material in and out of cell.
