Structure of the cell

Cards (40)

  • How much smaller is a prokaryotic cell than a eukaryotic cell?
    Ten times
  • What does a eukaryotic cell have that a prokaryotic cell doesn't?
    A neucleus and organelles
  • What do eukaryotic and prokaryotic cells both have?

    DNA
  • What is the cell wall made or also known as?
    Peptidoglycan
  • What does the envelope of a cell contain?
    A cell membrane, cell wall (pep), and outer membrane
  • What does the envelope in the cell separate?
    The inside from the outside of the cell
  • What is cytoplasm made of?
    Water and proteins
  • True or False: A prokaryotic cell is a bacterial cell?
    True
  • What do prokaryotes have instead of a nucleus?
    A nucleoid region
  • Describe inclusions?
    They're membrane enclosed storage areas, e.g. vacuoles
  • What do storage granules store?
    Excess material, such as excess water and sugars
  • What are vacuoles?
    Storage granules/structures that store excess material
  • Does a gram neg or gram pos cell contain an outer membrane?
    Gram neg
  • How's the peptidoglycan layer different in the gram pos cell different?
    It's thicker and made of different acids
  • What do the gram pos and gram neg cell both have in common?
    They both have an inner cell membrane
  • Why do myoplams bacteria have varying shapes?
    They have no cell wall
  • What does the cell wall do to a cell (form)?
    It gives it its shape
  • What's the function of porins in the gram- cell?
    They're channels that allow materials to go through
  • In which organisms is the peptidoglycan layer only found?
    Bacterial cells
  • What does pencillin inhibit?
    Cell wall formation
  • Why are the sugars strung together *NAM/NAG?
    Due to peptido
  • What's the function of pili and fimbrae?
    Fimbrae is for attachment and Pili is for mating
  • Why are fimbrae also referred to as appendages?
    Because they're sticking out of the cell
  • Where are cilia only found (cells)?
    Eukaryotic cells
  • What do s.mutans use adhesins for?What else do they use for attachment?
    To stick to teeth and the slime layer
  • What's the function of flagella?
    Movement
  • What is conjugation?
    The movement of DNA from one cell to another
  • How do Bacteria move thru flagella?
    Taxis
  • Desiccation?
    The process of removing moisture from something.
  • What bacteria causes pneumonia?
    Streptococcus pneumoniae,
  • What bacteria causes tooth decay ?
    S.mutans
  • What is the slime layer associated with on teeth?
    Biofilm
  • What is an endospore?Why do bacteria form this?
    An endospore is a highly resistant structure. Bacteria form endospores as a survival strategy to withstand harsh environmental conditions.
  • What cell forms endospores?
    Vegetative cells
  • Define sporogenisis?
    Formation of endospores
  • Which type of bacteria typically form endospores?
    Bacillus and Clostridium
  • What is the only way to destroy endospores?
    Through high temperatures (121 C) and pressures (15-20 lbs)
  • Do endospores reproduce? Yes or No?
    No
  • Describe the shapes of bacteria?
    Coccus=round; bacillus=rod (pill); spiral=curved
  • What are ways bacteria grow?
    Single; diplo (in pairs); Strepto (chains); Staphylo (grape shape)
