5 Multiple choice questions

  1. No nucleus
    DNA-one circular chromosome
    DNA not associated with histones
    No membrane enclosed organelles
    Divide by binary fission

    DNA enclosed in nucleus, multiple linear chromosomes DNA associated with histones,non-histone proteins
    Membrane enclosed organelles
    Require mechanisms
  2. Contain digestive enzymes
  3. ...
  4. Temporary storage organelles involved in transport by the processes of endocytosis/exocytosis

5 True/False questions

  1. ChloroplastsContain own DNAand reproduce by dividing in two.
    Thought to derive from bacteria that were engulfed by some ancestor of present-day eucaryotic cells, creating a symbiotic relationship.
    Contain chlorophyll/enzymes involved in photosynthesis to generate sugar and oxygen.
    Generate food and oxygen for mitochondria to use.

          

  2. Archaea can be extremophilic procaryotes; methanogens, halophiles, or hyperthermophiles...

          

  3. RibosomesProtein synthesis

          

  4. Endoplasmic ReticulumIrregular maze of interconnected spaces enclosed by a membrane that transports material through-out the cell
    -Smooth ER:synthesis of lipids, carbs., steroids
    -Rough ER: protein synthesis through ribosomes

          

  5. CytoplasmContain own DNAand reproduce by dividing in two.
    Thought to derive from bacteria that were engulfed by some ancestor of present-day eucaryotic cells, creating a symbiotic relationship.
    Contain chlorophyll/enzymes involved in photosynthesis to generate sugar and oxygen.
    Generate food and oxygen for mitochondria to use.
