Answer:
1.Knowing the names of the different parts of a microscope is important because it helps you communicate clearly with students or colleagues. Remembering the different parts is easy if you keep a labeled diagram with you and make sure you always use the proper terms when referring to the different parts of a microscope.
2.The microscope arm connects the eyepiece tube to the base. This is the part you should hold when transporting a microscope.
3.The base acts as the stand and support of the microscope. The arm functions as a handle when carrying the microscope properly and it connects the upper and lower parts of the microscope.
4.It is a U-shaped structure and supports the entire weight of the compound microscope. It is a vertical projection. This stands by resting on the base and supports the stage.
