Question

The occurrence of air bubbles while observing the cells in a matchstick under a microscope is avoided because

• A. It affects the visibility
• B. It is deeply stained
• C. It is located at the periphery
• D. None of the above

Answer 1

The correct option is A It affects the visibility

Robert Hooke performed the experiment in which the cells of the matchstick were observed under the microscope. The section of the matchstick was placed on the slide and covered with the coverslip. The coverslip should be placed properly without the introduction of any air bubble. The presence of the air bubble will reduce the visibility and the image of the cells will not be clear.

Thus, the correct answer is option A.
