Why safranin and glycerin are used to prepare a temporary mount of a leaf peel?

Safranin and glycerin are used in preparing a temporary mount of a leaf peel to enhance visibility and preserve the specimen. Safranin serves as a stain that highlights cellular structures, making them more discernible under a microscope. Glycerin acts as a mounting medium that maintains moisture and prevents the specimen from drying out, allowing for clearer observation of the leaf's anatomy. Together, they facilitate better study of the leaf's cellular features.
