Part 3: Plant Cells. Prepare wet mounts of an onion cell and an Elodea leaf cell and observe both under the microscope.Prepare the onion cells in hypotonic solution: b) Peel a thin layer of epidermis from a red surface of the onion. c) Place it on the slide. Add 1-2 drops of distilled water to cover the tissue. Place a coverslip over the tissue. Prepare the onion cells in hypertonic solution: d) Peel a thin layer of epidermis from a red surface of the onion. Place your metric ruler on the microscope stage, and move it into a position where you can see it clearly. Align one side of the ruler with the left edge of the field of view, and measure the entire field of view. This measurement is typically 1.4mm to 1.5mm. Given that 1mm equals 1,000 microns, 1.4mm equals 1,400 microns.
Place the covered blood smear on the microscope stage with the coverslip facing the objective lens and focus until blood cells appear. Red blood cells are the most common, measuring approximately 0.007mm in diameter. White blood cells are somewhat larger and more difficult to detect because they are white.

The cells in this slide will be in various stages of mitosis. Using the techniques you have just learned on the “e”, bring your onion cells into focus at 4x, then proceed to the 10x and 40x stages. At 40x magnification, you should be able to visualize the chromosomes inside the onion cell. With this microscope you can obtain four different magnifications: 40x, 100x, 400x and 1000x. The field of view when using the 10x objective (100x total magnification) is 2 mm. If 8 plant cells extend across the field of view (2 mm), then each cell is 2/8 or 0.25 mm long.Look at the slide under your microscope starting at low power. Look ...

The nucleus at the central part of the cheek cell contains DNA. When a drop of methylene blue is introduced, the nucleus is stained, which makes it stand out and be clearly seen under the microscope. Although the entire cell appears light blue in color, the nucleus at the central part of the cell is much darker, which allows it to be identified.
For onion skin cells, under 100X magnification, we are able to identify the cell wall, cell membrane and nuclei clearer than under 40X magnification. We did find that the onion skin cells have a much more regular shape than the red blood cells because they have the cell wall that is made up from cellulose to maintain its shape.Observing Onion Cells– Step by step instructions on preparing your onion sample, including staining the specimen and then observing it under the micrscope. 3 Easy Steps to Observing Pond Life under a Microscope– How to collect and prepare a wet mount slide of pond water in order to see microscopic organisms.
