Answer #1

FUNCTIONS OF PARTS OF COMPOUND AND DISSECTING MICROSCOPE

Ocular - The eyepiece, or ocular lens, is a cylinder containing two or more lenses; its function is to bring the image into focus for the eye.

Objectives - Objective lens on a microscope collects the light emerging from the sample and focuses it into the objective turret. Its primary role is to increase the magnification used for viewing.

Condenser - The condenser is a lens designed to focus light from the illumination source onto the sample.

iris diaphragm - Adjusts the amount of light that reaches the specimen.

Stage - The flat platform where the slide is placed.

Coarse adjusment - The coarse adjustment is used for focusing on an image when you are using the LOW or MEDIUM power objectives.

Fine adjustment - used for focusing on an image when you are using HIGH power objectives.
