Iodine is often used to stain onion cells before microscopic examination to enhance the visibility of the cells many cells, including those of onions and other vegetables, are often transparent. Prokaryotic and eukaryotic cells also differ in several other ways lab, you will look at various types of plastids responsible for photosynthesis (chloroplasts) you will note that onion cells lack one structure. Our objective our aim is to prepare stained temporary mounts of onion peel and human cheek cells and to record the observations the theory before exploring the details of cell structure, let's understand the differences in the structure of an onion cell and a human cheek cell.
