Center the wet mount of cheek cells under the microscope. Turn the lower power objective into position and bring the cheek cells into focus. Draw what you see in the appropriate box below. When you find cheek cells, examine them on high power, noting (and drawing) their shape and any visible cell structures in the appropriate boxes below:2. Place the carefully prepared microscope slide in position and keep in place firmly gripped with the clips. 3. Look through the microscope’s eyepiece and then move the focus knob carefully for the image to come into clear focus. 4. Slightly adjust the microscope’s condenser and amount of illumination for optimum light intensity.
