Which paragraph describes the correct procedure for preparing a stained wet mount of onion epidermis?

Answers

An onion is made-up of layers, which is separated by a thin skin or membrane. The cells are easily visible under a high power, compound microscope and the preparation of a thin section is straightforward.  The correct procedure for preparing a stained wet mount of onion epidermis are as follows. First, place a piece of thin onion epidermis on a slide. Second, add one drop of water and put one edge of a coverslip in the water drop, and then slowly lower the opposite edge to the water. Third, put one drop of stain at one edge of the coverslip and put a piece of paper towel at the opposite side of the coverslip. Lastly, allow the towel to absorb some water so that the stain will move under the coverslip and view it under a microscope.
