Lesson 3 quiz
1. The electron microscope has been particularly useful in studying prokaryotes, because electrons can penetrate tough prokaryotic cell walls. ~prokaryotes are so small. prokaryotes move so quickly they are hard to photograph. their organelles are small and tightly packed together.
2. Which of the following terms is most closely associated with "resolving power"? ~Clarity Larger size Greater color Lighter image
3. The person who first used the term cell to describe the basic unit of life was Anton Van Leeuwenhoek. James Watson. Louis Pasteur. ~Robert Hooke.
4. Which of the following is true of prokaryotic cells? ~They have no nucleus. They have mitochondria. They have an endoplasmic reticulum. Plant cells are one example.
5. Which of the following consist of prokaryotic cells Plants and animals Bacteria and archaea ~Plants, fungi, bacteria and archaea Plants, bacteria and archaea
6. The cells of a bee and an elephant are, on average, the same small size; an elephant just contains more cells. What is the main advantage of a small cell size? Small cells are less likely to burst than large cells. It takes less energy to make an organism out of small cells. ~A small cell has a larger surface area-to-volume ratio than a large cell. Small cells require less oxygen than large cells.
7. Ribosomes are found on the surface of this structure. Central Vacuole Rough ER Chloroplasts ~Golgi Bodies
8. The function of the nucleus is to produce proteins. contain the cytoplasm. ~contain and replicate DNA. add sugars to proteins.
9. The function of ribosomes is to synthesize RNA. DNA. lipids. ~protein.
10. Which of the following structures maintains cell shape, anchors the organelles, and moves parts of the cell? Hydrogen bonds ~Cytoskeleton Cilia Golgi complex
11. One of the main structural components of plant cell walls is ~cellulose. glucose. mitochondria.
