Review Assignment: complete on a separate piece of notebook paper. 1) For each of the following, indicate which type of microscope you would use (and why): A) the changes in shape of a living human white blood cell; B) the details of surface texture of a human hair; C) the detailed structure of an organelle in the cytoplasm of a human liver cell. 2) Explain how and why phospholipids tend to organize when in an aqueous environment. 3) Describe the structure and function of the various proteins associated with the cell membrane and how they provide for the interaction of the cell with the outside environment (i.e. transport, cell-cell recognition, receive & respond to signals, etc.). 4) Compare and contrast the cellular characteristics of prokaryotes and eukaryotes. 5) Compare and contrast the cellular characteristics of plant and animal cells. 6) Describe how an animal cell AND a plant cell might will react when placed in either a hypertonic, hypotonic, or isotonic environment. 7) After very small viruses infect a plant cell by crossing its membrane, the viruses often spread rapidly throughout the entire plant without crossing additional membranes. Explain how this occurs. 8) Consider the following organelles: mitochondrion, chloroplast, ribosome, lysosome, peroxisome. Which organelle does not belong in the list? Why not? 9) What is the relationship of chromosomes to chromatin? 10) For each structure, describe 2 functions: A) rough endoplasmic reticulum B) smooth endoplasmic reticulum C) microtubules D) microfilaments E) intermediate filaments 11) Which component of the cytoskeleton is most important in: A) holding the nucleus in place? B) guiding transport vesicles from the the Golgi to the plasma membrane? C) amoeboid movement? D) moving flagella and cilia? E) muscle contraction? F) reinforcing the shape of a cell? 12) Describe the function of each intercellular junction listed below: A) plasmodesmata B) tight junctions C) desmosomes D) gap junctions **REVIEW Study Questions from CH 6 & 7; cell parts chart & cell processes chart; Lab 1A & 1B Prelab, concepts & results Online resources (optional for you to check out / use for study & review): Cell Structure and Function http://learn.genetics.utah.edu/content/begin/cells/insideacell/ (cool animation of cell structure and function) http://www.johnkyrk.com/CellIndex.html (internal cell structures and functions) http://www.biology.arizona.edu/cell_bio/tutorials/cells/cells1.html (tutorial with questions about cells) http://www.wiley.com/legacy/college/boyer/0470003790/animations/cell_structure/cell_structure.htm (compare and contrast prokaryotic and eukaryotic cells) http://www.cellsalive.com/cells/3dcell.htm (review of cell parts) http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/A/Apoptosis.html (interesting information about how and when cells die: apoptosis) Cell Membrane & Transport http://www.johnkyrk.com/cellmembrane.html (cell membrane animation) http://www.susanahalpine.com/anim/Life/memb.htm (another membrane model) http://highered.mcgraw-hill.com/sites/0072437316/student_view0/chapter6/animations.html# (animations of different types of cell transport)  ':<=@ABCTmnopC ^ 4 h i j y z ߼tgtgtgtghkdCJOJQJ\^JhtwCJOJQJ\^JhtwCJOJQJ^JhkdCJOJQJ^Jhkd5>*CJOJQJ\^J%hkdhkd5>*CJOJQJ\^JhkdhkdCJOJQJ^Jh"OJQJ^JhfuvOJQJ^JhkdhkdOJQJ^JhkdOJQJ^Jh`OJQJ^J'BCop - < _  . 5 i $Ifgdkd$If$a$  8 9 U v w  ̼udPdPdPddBhdQhtw56OJQJ&hdQhtwCJOJQJ\]^JaJ hdQhtwCJOJQJ^JaJ"hdQhtw5CJOJQJ\^JhdQhtwCJOJQJ\^J&hdQhtw5CJOJQJ\^JaJ h:5CJOJQJ\^JaJhw|5>*CJOJQJ\^Jhkd5>*CJOJQJ\^J%hkdhkd5>*CJOJQJ\^JhkdhkdCJOJQJ\^J ym $$Ifa$gd: $$Ifa$gddQxkd$$Ifl4 0(??064 laf4  , 8 {{{{ $Ifgd={kd$$Ifl0\(dd t0644 laytdQ8 9 M U j v ^UUUU $Ifgd=kd*$$Ifl\ *\(2 2 2 2 t0644 laytdQv w ^UUUU $Ifgd=kd$$Ifl\ *\(2 2 2 2 t0644 laytdQ ^UUUU $Ifgd=kd`$$Ifl\ *\(2 2 2 2 t0644 laytdQ   # ^UULL $Ifgd= $Ifgd=kd$$Ifl\ *\(2 2 2 2 t0644 laytdQ # $ .
