  7. Which of the following is not a true statement about the cytoskeleton?
    1. It helps support cells.
    2. Once formed, the cytoskeleton is permanent and unchanging.
    3. It is composed of microfilaments, microtubules, and intermediate filaments.
    4. It plays an important role in cell movement.
    5. It is composed of proteins.

  8. In the understanding of cell function and structure, which of the following was most instrumental to advance the knowledge?
    1. microscope
    2. probe
    3. Pasteur pipette
    4. Bunsen burner

  9. One large cell is less efficient than many small cells because
    1. Small cells have greater surface area to volume ratios.
    2. Diffusion cannot occur in large cells.
    3. Large cells have fewer reactions occurring.
    4. Many small cells do not produce as much waste as a large cell of the same volume.
    5. Small cells move faster than big cells.

    2. "before the nucleus"
    3. "true nucleus"
    4. "small nucleus"
    5. "before the cell"

  11. Prokaryotes and eukaryotes are different because
    1. Prokaryotes have RNA; eukaryotes have DNA.
    2. Prokaryotes have DNA; eukaryotes have RNA.
    3. Prokaryotes have a nucleus; eukaryotes have a nucleoid.
    4. Prokaryotes have a nucleoid; eukaryotes have a nucleus.
    5. Prokaryotes have a cell wall; eukaryotes do not.

  12. Chloroplasts are found in organisms in which of the following paired kingdoms?

    3. chloroplast and nucleus
    4. nucleus and lysosome
    5. lysosome and mitochondrion

  14. In a cell filled with broken lysosomes, what happens to the cell that created them?
    1. The enzymes digest any surplus cellular components.
    2. The cell is destroyed.
    3. The cell immediately produces a new membrane to recapture the lost enzymes.
    4. The cell channels the enzymes to the cell surface for removal from the cell.
    5. Nothing; the enzymes cannot function in the cell.

  15. Which part of the cell plays an essential role during cell division?
    1. ribosomes
    2. mitochondria
    3. cytoskeleton
    4. ER
