5 Written questions

5 Matching questions

  1. Largest cell (volume)
  2. All organisms carry out gene expression:
    -flow of genetic info.
    -allows for growth/processes
  3. Largest cell (length)
  4. Endoplasmic Reticulum
  5. Bacteria can be non-pathogenic, photoautotrophic, or pathogenic procaryotes
  1. a Giant squid nerve cell (39ft)
  2. b Replication--->Transcription--->Translation
  3. c 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
  4. d ...
  5. e Ostritch egg

5 Multiple choice questions

  1. ...
  2. Packages/modifies molecules received from ER then transports
  3. Maintain 3-D structure of the cell
    Movement of organelles (microtubules)
    Generate contractile forces (actin filaments)
    Strengthen cell (intermediate filaments)
  4. The ancestral eucaryotic cell was a predator that fed by capturing other cells. Such a way of life requires a large size, a flexible membrane, and a cytoskeleton to help the cell move and eat. The nuclear compartment may have evolved to keep the DNA segregated from this physical and chemical hurly-burly, so as to allow more delicate and complex control of the way the cell reads out its genetic information.
  5. E. Coli., brewers yeast, Arabidopsis, fly, mouse, fish, worm, human
    Easy to grow

5 True/False questions

  1. ChloroplastsConsists of cytosol--->jelly-like mixture
    Consists of organelles

          

  2. 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.

          

  3. NucleusTemporary storage organelles involved in transport by the processes of endocytosis/exocytosis

          

  4. Procaryote = before nucleusContain Bacteria/Archaea

          

  5. RibosomesProtein synthesis
