2. What are lysosomes?

  • External organelles that keep cells stationary
  • Vesicles that play a key role in protein synthesis
  • Specialised forms of vesicles containing hydrolytic enzymes (digestive enzymes)
  • Specialised digestive enzymes

3. What is exocytosis?

  • When materials are transported out of the cell via secretory vesicles
  • When materials are transported into the cell via secretory vesicles
  • The process in which cells get rid of or burn excess energy

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

  • 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 smooth ER is normally much larger than the rough ER
  • The rough ER is attaced to the nucleus, and the smooth ER is attached to the cell membrane
