Coverslip is put on the mounted material on a slide very gently to

• A. Avoid the crushing of mounted material
• B. Avoid the entry of air bubbles
• C. Avoid oozing of stain
• D. Avoid oozing of glycerine

Answer 1

The correct option is B Avoid the entry of air bubbles

Coverslip is fixed on the microscopic slide, where the sample is mounted.
It is mounted in such a way that no air bubbles are trapped.
When air bubbles are trapped, the microscopic view will not look clear and the bubbles will be seen in the view.
