Electron Micrographs**

Below is a collection of electron micrographs with labelled subcellular structures that you should be able to identify. Also, be sure to observe any electron micrographs which are made available in the laboratory by the instructor. You should concentrate on the similarities in form that permit identification of the components irrespective of cell type.

Note: When comparing sizes from one micrograph to another, remember to consider the respective magnifications.
