Quiz – Microscopes, Cell Theory & Organelles

What type of microscope must have Milan used to generate this image of adenoviruses?

• Compound light microscope

• Dissection microscope

• Scanning electron microscope

• Transmission electron microscope

If a student needed to view a cell structure at much higher magnification (such as 10,000x or 100,000x magnified), how would the student be able to generate a clear image?

• They should use a brighter light source to illuminate the slide

• They should use an electron microscope, such as a SEM or TEM

• They should use a lower power objective lens on the microscope

• They should stack the eyepiece lenses from multiple light microscopes

Both euglena and cyanobacteria are photosynthetic unicellular organisms found in pond water. Euglena, however, is eukaryotic while cyanobacteria are prokaryotic. What feature distinguishes euglena from cyanobacteria?

• The ability to reproduce asexually

• The presence of ribosomes in the cells

• The ability to maintain homeostasis

• The presence of a nuclear membrane

If a cell's lysosomes become damaged, which of the following would MOST LIKELY occur?

• The cell would produce excessive proteins

• The cell would be less able to break down molecules within the cell

• The would slow down the process of photosynthesis

• The cell would be less able to regulate the amount of fluid in its cytoplasm

At what point does a theory become a law?

• Once the evidence and data have been accepted in the scientific community, it becomes a law.

• Theories do not become laws.

• As long as there have not been any experiments or other observed data that refute the theory it can become a law.

• If there have been enough experiments that support the theory, it will become a law.

The prefix "micro" refers to tiny, and the suffix "scope" refers to view or look at. Microscopes are tools used to enlarge images of small objects so they can be studied more effectively. There are various types of microscopes, depending on the type of image that the scientist wants to view. Therefore, if a scientist is attempting to view the external surface of a bacterial cell with an emphasis on surface detail, what statement BEST explains what type of microscope to select in this scenario, with a rationale for using that particular kind of microscope?

• A Scanning Electron Microscope (SEM) because it produces images by scanning specimens with a beam of electrons in order to provide a surface image of the bacteria.

• A Transmission Electron Microscope (TEM) because it produces images by transmitting a beam of electrons through the bacteria

• A Compound Light Microscope because it produces images with two types of lenses

• A Dissection Microscope because the lower magnification enables the user to manipulate the small bacteria

Which of the following microscopes would be BEST to observe a living organism in pond water?

• scanning electron microscope

• transmission electron microscope

• compound light microscope

• either scanning or transmission electron microscope
