  1. What is the Cell Theory?
    • All organisms are composed of one or more cells.
    • Cells are the smallest living units of all living organisms.
    • Cells arise only by division of a previously existing cell (mitosis).
  2. All organisms are composed of what?
    One or more cell.
  3. What are the smallest living units of all living organisms?
    Cells.
  4. Cells arise only by what?
    The division of a previously existing cell (through mitosis).
  5. What is a macromolecule?
    A larger molecule that is a polymer.
  6. What is a polymer?
    Something that is made of many parts.
  7. Where did cells form?
    Earth's ancient anoxic atmosphere with high temperatures, ample hydrogen, and very little oxygen.
  8. Where did the monomer's come together so the cells could form?
    • Ocean's edge
    • Within or on clay
    • Deep-sea vents
  9. What test successfully produced molecules?
    Urey-Miller Experiments
  10. What process joins monomers into polymers?
    Dehydration Synthesis
  11. What is the Cell Membrane Assembly process?
    Amino Acids reaction is sped by the heated clay as a catalyst. Then they enter the proteinoids' selectively permiable membranes.
  12. Fact: Monomers form into short RNA strands. The self-replications of some short RNA polymers.
    Yep.
