2. Which are three features of plant cell walls?

  • Are rigid structures, allow the plant cell to change shape, and are partially permeable.
  • Made of cellulose, are freely permeable, and are on the outside of the cell membrane
  • Made of cellulose, are partially permeable, and are on the outside of the cell membrane
  • Found inside the cell membrane, freely permeable, and make the plant cell rigid

3. What are microtubules?

  • A component of the cytoskeleton that can break down the cell and rebuild it again during complex cellular processes
  • Contractile fibres formed from the protein actin
  • A component of the cytoskeleton that forms a scaffold like structure that determines the shape of the cell
  • Tiny organelles on the surface of the cell that record information about the cells environment

4. I'm an organelle found in plant cells. I contain an inner membrane that's arranged in flattened sacs. Which organelle am i?

  • A centriole
  • Secretory vesicles
  • The chloroplast
  • The mitrochondria

5. What is the difference in structure between the smooth endoplasmic reticulum and the rough endoplasmic reticulum?

  • The smooth ER is normally much larger than the rough ER
  • The rough ER has centrioles attached to it, and the smooth ER does not
  • The rough ER has ribosomes attached to it, and the smoothh ER does not
  • The rough ER is attaced to the nucleus, and the smooth ER is attached to the cell membrane
