8.1 and 8.2 Test Review

Which type of microscopes require the specimen to be chemically preserved when viewing them? 

• light microscope

• transmission electron microscope

• scanning electron microscope

• chemical stain microscope

• compound light microscope

Dr. Boatie is looking through a microscope and determines that the cells in his sample are prokaryotic cells. What are some likely characteristics of the cells he is looking at? 

• they have membrane-bound organelles

• their DNA is in a nucleoid that is floating in the cytoplasm

• they are quite large cells

• they are complex in comparison to eukaryotic cells

• they are unicellular

Which microscope provides a detailed 3D image of the surface of a specimen?

• light microscope

• transmission electron microscope

• scanning electron microscope

• radiograph microscope

You are viewing cells under a microscope. Which of the following characteristics would tell you that the are eukaryotic cells?

• they are more complex than prokaryotic cells

• they have membrane-bound organelles

• they have a clearly visible nucleus

• they belong to a multicellular organism

• they are smaller than most prokaryotic cells

What is typically the most visible organelle in a eukaryotic cell stained with methylene blue?

• mitochondria

• chloroplasts

• nucleus

• cell wall

• lysosomes

Where are ribosomes made?

• mitochondria

• vacuoles

• cytoskeleton

• nucleolus

The rough endoplasmic reticulum...

• is studded with ribosomes

• make membrane lipids and carbohydrates

• generates energy from the sun

• makes and modifies proteins that will be exported from the cell

• regulates what enters and exits the cell

You are trying to view the details of an incredibly small bacterial cell that is 1 micrometer wide. What kind of microscope(s) should you try using for the best result? 

• scanning electron microscope

• light microscope

• compound light microscope

• transmission electron microscope

What is the function of ribosomes?

• to break down old unused organelles

• to make membrane lipids

• to synthesize proteins

• to store cellular waste

• to synthesize sugars for energy use

Why does the nuclear envelope have pores in it?

• they allow the nucleus to expand during cell division without rupturing

• they allow messages and instructions to move into and out of the nucleus

• they allow mitochondria to move into the nucleus

• they allow the energy that the nucleus produces to leave and be used elsewhere in the cell
