Under a light microscope, the cell membrane, nucleus and cytoplasm of a cheek cell (animal cell) can be observed. Observing Onion Cells under a Microscope - Blog, She Wrote you'll need to stain the onion cells before you observe them under the microscope. There are different types of stains depending on what type of cell you are going to look at. Iodine - dark stain that colors starches in cells. In an onion cell, it will make the cell wall more visible. It provides some contrast for viewing under a microscope. PDF Onion Cells - Investigation - Exploring Nature 1. Observe the onion tissue under the microscope at 4x, 10x and 40x with lots of light (open diaphragm). 2. Then slowly close the diaphragm while observing the image to find the best light for seeing cellular details. 3. Draw a section of onion skin cells at 10x magnification. 4. Switch to 40x and draw one cell and label it. Microscope Cell Lab: Cheek, Onion, Zebrina - SchoolWorkHelper The onion epidermis cell is the only cell that has a cell wall. In addition, it is the only cell that has a chloroplast, where photosynthesis can happen. The cheek epithelium cell is the only one that has centrioles, the barrel-shaped organelle that is responsible for helping organize chromosomes during cell division.
