  1. What is lateral gene transfer?
    • transfer
    • of DNA from one organism to another that is not its offspring)
  2. what did eukaryotic cells orgiginate from?
    ancient prokaryotic cells
  3. what is the sequence of events that eukaryotic cells went through?
    loss of cell wall, origin of cytoskeleton, ribosomes became associated with internal membranes, digestive vesicles formed, acquired mitochondria and chloroplasts
  4. term for engulfing
    phagocytosis
  5. endosymbiotic theory
    originated as bacterial cells, earlies eukaryotes acquired mitochondria by engulfing, some eukaryotes acquired chloroplasts by engulfing ancestral cyanobacteria
  6. what organelle is referred to as (suicide sac)
    lysosomes
  7. why are lysosomes called suicide sacs?
    if they rupture, it would digest the cell
  8. how are lysosomes made?
    small membrane sacs are "pinched" from golgi apparatus
  9. what do lysosomes contain?
    digestive enzymes- very powerful
  10. what is the function of lysosomes?
    digest food and damaged organelles
  11. what is the site of cellular respiration?
    mitochondria
  12. what do mitochondria contain?
    their own ribosomes and DNA (mDNA)
  13. what is found in all eukaryotic cells?
    mitochondria
  14. describe mitochondria membranes
    smooth outer membrane, folded inner membrane
  15. what are the sites of photosynthesis?
    chloroplasts
  16. what do chloroplasts contain?
    their own DNA (cDNA) which codes proteins that are involved in photosynthesis.
  17. describe membranes of chloroplasts
    smooth inner and outer membrane
  18. where are chloroplasts found?
    only in some plant and algal (protist) cells
  19. symbiotic relationship where both benefit?
    mutualism
  20. What are the large membrane sacs?
    vacuoles
  21. what are the tiny membrane sacs?
    vescicles
  22. what is the function of vacuoles?
    to transport and store material (water, pigments, poisons)
  23. why do vacuoles produce and store poison?
    to protect themselves
  24. plant cells have?
    cell wall, chloroplasts, and vacuoles
  25. what do animal cells have?
    centrioles
