So to view the cells we add acetic orecin stain by putting it in a watch glass with the root tips and putting it on a hot plate. Why do this as we also add a few drops of the stain onto the slide?

Acetic orcein will stain the chromosomes dark red and fix the cells, stopping mitosis.The cellulose walls of plant cells are held together by pectins such as calcium pectate. The root tip is heated with acid to break up the tissues into individual cells.
