The flashcards below were created by user KaZuma_t3 on FreezingBlue Flashcards. What would you like to do?


  1. define eukaryotic
    • unicellular organism with membrane-bound nucleus and organelles
    • generally larger and more complex than prokaryotic cells
  2. define prokaryotic
    microscopic, unicellular organism without a nucleus or other membrane-bound organelles
  3. define ribosomes
    simple cell organelle that helps manufacture proteins
  4. define cytoskeleton
    supporting network of protein fibers that provide a framework for  the cell within the cytoplasm
  5. define unicellular
    a living organism that is only one cell big
  6. define multicellular
    a living organism that has many cells interesting in tissues and organ systems
  7. similarities between prokaryotic and eukaryotic cells (5)
    • contain DNA
    • similar pattern of metabolism
    • they both have cell membranes
    • diverse in forms
    • some are unicellular organisms
  8. differences between prokaryotic (5) and eukaryotic (7)
    prokaryotic

    • no nucleus
    • smaller
    • has a thick cell wall
    • no cytoskeleton
    • unicellular 

    eukaryotic 

    • are 10x larger in diameter
    • have a true nucleus
    • membrane enclosed organelles
    • have a cytoskeleton 
    • multicellular 
    • may or may not have a cell wall
    • present in all living organisms
  9. what are the three shapes of bacterial cells (3)
    • cocci 
    • bacilli
    • spirilla
  10. identify and explain the two domains in which bacterial cells are found (2)
    • domain archea - ancient life that live in extreme conditions
    • domain eubacteria - true bacteria
  11. what two categories of bacteria are formed from bacteria and how did they differ
    • anerobic: live without oxygen
    • aerobic: need oxygen
  12. why are bacteria in the human body beneficial (4)
    • decompose dead matter in ecosystems
    • e. coli in small intestine, helps digest food we can't and releases vitamins
    • lactobacillus, bacteria that ingests lactose in milk and releases an acid to make yogurt
    • nitrogen-fixing bacteria (rhizobia) change inorganic N2 into nitrates for plants
  13. why are bacteria in the human body harmful (3)
    • cyanobacteria causes damage and slime in waterways
    • food poisoning - cholera from contaminated water
    • respiratory diseases (tuberculosis and pneumonia)
  14. why are viruses not living organisms (3)
    • they are not made of cells
    • they can't make proteins
    • can't reproduce without invading a host cell
  15. define vaccine, how can it protect against disease
    preparation of killed or weakened pathogens introduced into the body to produce immunity
  16. why do vaccines not protect against all viral diseases (2)
    • do not protect against viruses with varying protein
    • if surface protein mutate often, new changes are not recognized by the immune system
  17. what could happen to control and eliminate an epidemic (4)
    • the virus must be identified
    • route of transmission must be determined in order to prevent the spread of the disease
    • you could quarantine if necessary
    • medication
  18. if you opened up a virus, what would you find
    a core of dna or rna surrounded by a protein coat
  19. where does viral reproduction occur
    viral reproduction occurs in a host cell
  20. characteristics of monera
