Answer 1

Answer:

provides support to cells

Answer 2

C. Prevents drying.

EXPLANATION:

Glycerine is isotonic with cell sap. For this reason, the cells used for the mount do not shrink or swell and can be viewed in their natural form. Additionally, glycerin moistens the mounting material and prevents it from drying out.

Steps that one can follow for the preparation of a temporary mount of a stained leaf peel are as follows:

• First, peel the underside of the leaves.

• After that, the petri dish is washed by dropping it into a petri dish with water, and a drop of safranin is added as a coloring agent.
• Transfer the stained dish to a clean glass slide, add 1 drop of glycerine, and place a coverslip on top.
