Onion Cells under the Microscope

This is an easy and fun activity that will allow your student to learn about onion cell structure. Students have the opportunity to experiment and observe the onion membrane with different stains (methylene blue and iodine). The video specifically shows staining with iodine. you can also observe the onion cells under a microscope without the stain and observe the differences. Having observed the onion cell under the microscope, students will be able to learn the differences between animal and plant cells in addition to the function of the different parts of the cell.
