Question

Bottles containing the undermentioned liquids were available in the laboratory. Which liquid did a student use for putting a drop on the slide before placing the coverslip while preparing the temporary mount of leaf epidermal peel?
(1) Water
(2) Safranin
(3) Glycerine
(4) Iodine

Solution

The student must have put a drop of glycerine on the slide before placing the coverslip on the slide. Glycerine is a viscous liquid which prevents the specimen from drying out and keeps it moist for longer duration. Also glycerine tends to refract light due to its refractive nature. As a result of which, the image appears clearer under the microscope.

Hence, the correct answer is option 3.
