  1. Define:
    Bacilli
    Rod-shaped bacteria
  2. Define:
    Cocci
    Sphere-shaped bacteria
  3. Define:
    Spirilla
    Spiral-shaped bacteria
  4. Define:
    Cell Membrane
    The protective outer covering of all cells that regulates the interaction between the cell and the environment.
  5. Define:
    Cell Wall
    The rigid structure that encloses, supports, and protects the cells of plants, algae, fungi, and most bacteria.
  6. Define:
    Cytoplasm
    Constantly moving gel-like mixture inside the cell membrane that contains heredity material and is the location of most of a cell's life processes.
  7. Define:
    DNA
    (Deoxyribonucleic acid) The genetic material of all organisms. It is made up of two twisted strands of sugar-phosphate molecules and nitrogen bases.
  8. Define:
    Flagella
    The long, thin whiplike structure that helps organisms move through moist or wet surroundings.
  9. Define:
    Ribosomes
    A small cytoplasmic structure on which cells make their own proteins.
  10. Define:
    Protein Coat
    The coiled or polyhedral structure, composed of proteins, that encloses the nucleic acid of a virus.
  11. Define:
    Nucleic Acid
    A thick-walled, protective structure produced by some bacteria when conditions are unfavorable for survival.
  12. Define:
    Anaerobic
    An organism that is adapted to living in environments that have no oxygen.
  13. Define:
    Aerobic
    An organism that uses oxygen when breaking down food.
  14. Define:
    Binary Fission
    The reproduction cycle of a bacteria cell. The cell replicates DNA, grows, then splits into two of the same exact cells.
  15. Define:
    The Lytic Cycle
    The reproduction cyle of a virus, where the virus attatches to the host cell, and injects genes into it.
  16. Define:
    Conjugation
    When bacteria send a thin line across, connecting to another bacteria, and exchanges genes.
  17. Define:
    Lysogenic
    When the virus enters the cell, then reproduces.
  18. Define:
    Pathogen
    Any disease-producing organism.
  19. Define:
    Antibiotics
    Chemicals produced by some bacteria that are used to limit the growth of other bacteria.
