Stomates (or stomas) are openings on the underside of a leaf, which allow gases to pass in and out of the leaf. The pictures show these stomates as narrow gaps. Two guard cells control the size of the opening. The guard cells have chloroplasts, which are visible as dark dots in the cell. During the [...]
A simple check of the refrigerator (or the super market) provides many safe sources for microorganisms to view under the microscope.
Observing human cells is a good introductory activity to learn heat-fixing and staining.
