-Two Microscopes - -Dissecting and Compound
-Dissecting Microscope - --Magnifying objects 1 mm or greater
-does not see fine surface details or features
-shines light ONTO object but magnifies to a lesser degree than Compound
-Advantage is to see whole thing at once rather than sections
-Compound Light Microscope - --To see cells, parts of cells, or small organisms
-Objects 10 nm-1 mm
-Light shines THROUGH object (makes it translucent)
-Advantage is to see object at much higher resolution
-Ocular - --Eye Piece
-Uppermost series of lense
-For magnification

-Holds objective lenses and allows them to move in place
-Low-power Objectives - --Smallest Objective
-Magnification 4x or 10x
-High-Power Objective - --Largest Objective
-40x
