  4. Golgi Apparatus
  1. a ...
  2. b Packages/modifies molecules received from ER then transports
  3. c Contain 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.
  4. d Temporary storage organelles involved in transport by the processes of endocytosis/exocytosis

5 Multiple Choice Questions

  1. Irregular 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
  2. Maintain 3-D structure of the cell
    Movement of organelles (microtubules)
    Generate contractile forces (actin filaments)
    Strengthen cell (intermediate filaments)
  3. Enclosed in the nuclear envelope, contains most of the cells molecules of DNA that later condense into chromosomes as a cell prepares to divide.
  4. Protein synthesis
  5. Consists of cytosol--->jelly-like mixture
    Consists of organelles

5 True/False Questions

  1. PeroxisomesContain digestive enzymes

          

  2. MitochondriaProtein synthesis

          

  3. Bacteria can be non-pathogenic, photoautotrophic, or pathogenic procaryotesNo 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

          

  4. Model OrganismsContain 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.

          

  5. Cell shape depends on functionSurface/volume ratio:volume increases faster than surface area.
    Nucleus(the brain): can only control certain amount of active cytoplasm.
