Image orientation in compound microscope is:
Compound microscope produces real inverted image. If slide moves right, image moves left.

The illuminator source in modern compound microscopes is:
Modern microscopes use built-in LED or halogen with intensity control. Old models used mirror reflecting daylight.
Ref: NCERT Biology, Class XI, Chapter 8: Illumination system in microscope.
The eyepiece (ocular lens) typically has a magnification of:
Standard eyepiece is 10x (wide-field WF10x). Some have 15x. Total magnification = eyepiece x objective.
Ref: NCERT Biology, Class XI, Chapter 8: Optical parts of microscope, eyepiece role.
Coarse adjustment knob is used for:
Coarse adjustment moves stage quickly. Should only be used at low power (10x) to avoid slide collision.
Ref: NCERT Biology Laboratory Manual, Class XI, Focusing mechanism and precautions.
The nosepiece (revolving turret) holds:
Nosepiece holds 3-5 objectives and rotates to bring desired objective into optical path with click-stop mechanism.
Ref: NCERT Biology, Class XI, Chapter 8: Objective lenses and nosepiece function.
A mechanical stage differs from a simple stage in that it:
Mechanical stage allows precise movement using coaxial knobs with vernier scale for relocating fields.
Ref: NCERT Biology Laboratory Manual, Class XI, Mechanical stage and scanning techniques.
Stage clips are important because they:
Clips prevent slide drift during observation and scanning. Without them, field of view shifts.
Ref: NCERT Biology Laboratory Manual, Class XI, Slide mounting and stage handling.
What is the function of the stage in a compound microscope?
Stage is the flat platform where slide is placed. Central aperture allows light to pass through specimen.
Ref: NCERT Biology, Class XI, Chapter 8: Practical microscopy, stage function.
The arm of the compound microscope is used for:
The arm is the curved structure that connects base and head. It is used for carrying and provides attachment for stage and focus mechanisms.
Ref: NCERT Biology Laboratory Manual, Class XI, Handling of compound microscope.
What is the primary function of the base of a compound microscope?
The base is the bottom-most part that supports the whole microscope and houses the illuminator in modern microscopes. It provides stability on the bench.
