1.	Write down the functions of parts of microscope.
Answer» 1. The support system consists of the base or foot rest which also holds the light source 2. The tube or the arm holds the optical system and also the coarse/fine adjustments. 3. The objectives are at the lower end of the tube and the eye pieces are at the upper end. 4. The objectives are attached to the revolving nose piece and can be shifted. The objectives are 10x (low power) 40x (high power) and 100x (oil immersion). 5. Below the objectives is the stage which holds the object/slide. The stage has a central hole through which the light passes. The stage may be fixed or movable. Below the stage is the iris/diaphragm which focuses the light. 6. The eye pieces are also of varying magnification; the commonly used one is 10 X. The eye pieces are situated in the binocular tube.
