WebMicrobiology The role of the medical assistant in specimen collection includes all of the following except : diagnosing the patient once test results are received. Bacteria that die in the presence of oxygen are called: anaerobes. Small structures in the cytoplasm of a cell are called: organelles. WebFixation and dehydration are important for preparing samples for both the TEM and the SEM. However, other aspects of sample preparation differ greatly because the two microscopes have different requirements. For TEM, samples must be cut into very thin cross-sections. This is to allow electrons to pass right through the sample.
