  • 1. 1.2.1 Draw a generalized prokaryotic cellas seen in electron micrographs.
  • 2. 1.3.1 Draw a diagram to show the ultrastructure of a generalized animal cell as seen in electron micrographs
  • 3. 1.4.1 Draw a diagram to show the fluid mosaic model of a biological membrane Note: include and label using these names -phospholipid bilayer (point out hydrophilic head and hydrophobic tail) -cholesterol -glycoproteins -integral proteins -peripheral proteinsMake sure to use term plasma membrane, notcell surface membrane
  • 4. 2.2.2 Draw the basic structure of a generalized amino acid no details about the R group are needed
  • 5. Glucose Ribose2.2.3 Draw the ring structure of glucose and ribose
  • 6. OCH3------(CH2)n--------C Generalized fatty acid OH 2.2.4 Draw the structure of glycerol and a generalized fatty acid *don’t forget the “n” after the (CH2) in the generalized fatty acid (n means, could be any number of that part of the molecule)
  • 7. A generalized dipeptide2.2.4 Draw the structure of a generalized dipeptide, showing the peptide linkage
  • 8. Key to this picture: 1. hydrogen bonds in PINK 2. Bases in green and purple 3. Sugar phosphate backbone in black Phosphates in yellow2.4.5 Draw a simple diagram of the molecular structure of DNA -show complementary C:G and A:T pairs -identify hydrogen bonds (hold bases together) -number of H-bonds between complementary bases not required -details of base structure not requiredYour diagram can be simple, just remember thatA and G are double rings; C and T are single rings.Sugar phosphate backbone goes on outside of “ladder”Bases are the “rungs of the ladder”hydrogen bonds between bases are in very center
  • 9. 4.1.14 Draw the carbon cycle to show the processes involved. Be sure to include: Point is to show -photosynthesis interaction of -respiration living organisms -fossilization and the biosphere (you could substitute the through processes word “fossilization” for of photosynthesis, “calcareous sediments” above respiration, -combustion (burning of fossil fossilization & fuels) combustion
  • 10. *4.2.2 Draw a graph showing the sigmoid (S-shaped) population growth curve *you could use “organisms” or “population size” for the Y axis as well. *S shape demonstrates that the population starts slow, rises exponentially, then plateaus at the carrying capacity of the environment
  • 11. Topic 5.1.4 Draw a diagram of the digestive system Be sure to include -mouth -liver -esophagus -pancreas -stomach -gall bladder -small intestine (I have blanked out the -large intestine items you don’t need that -anus were in this figure)
  • 12. 5.2.1 Draw a diagram of the heart showing all four chambers, associated blood vessels, and valves Include -all blood vessels connected directly to the heart -relative wall thickness of chambersSee also: Study guide handouts Page 48 (Page titleis “The Blood System” (given out during unit)
  • 13. 5.5.4 Draw a diagram of the ventilation system including trachea, bronchi, bronchioles, and lungsSee also study guide handout (given during unit)page 51, titled “Gas Exchange”
  • 14. MaleFemale5.7.1 Draw diagrams of the adult male and female reproductive systems see handouts page 54 titled “Reproductive Systems” given during unit
  • 15. 7.1.3 Draw the structure of a mitochondrion as seen in electron micrographs
  • 16. chloroplastenvelope be sure to include -thylakoid membranes -granum -inner membrane -outer membrane -starch grain -stroma containing 70s ribosomes (dots) -naked dna (dots or small circles) -lipid droplet (large dot in stroma) 7.2.1 Draw the structure of a chloroplast as seen in electron micrographs
  • 17. 7.2.7 Draw the action spectrum of photosynthesis
  • 18. 9.1.1 Draw the structure of testis tissue as seen using a light microscope (draw one seminiferous tubule in transverse section with adjacent interstitial cells. show outer basement membrane, spermatogonia, developing spermatozoa, and sertoli (nurse) cells interstitial cells spermatogonium primary spermatocyte immature spermatids mature spermatids secondary spermatocyte
  • 19. 9.1.4 Draw the structure of the ovary as seen using a light microscope -show primary oocytes (primordial follicles) -secondary oocyte in prophase II (preovulatory follicle) -corpus luteum -show also a follicle with egg being released
  • 20. Acrosome layer centrioles of follicle cells layer of first polar follicle cell cells haploid nucleus zona cortical pellucida granules cytoplasm (yolk)9.1.6 Draw the structure of a mature sperm and egg. See also handout p 92 titled “Gametes”
