13. Which is involved in genetic storage and information transfer? Which is a reactant of cellular respiration?Which molecule resembles a component of ADP/ATP?Which molecule contains the 4 major atoms found in protein? 11. A. B. C.

14. Macromolecules, monomeric units and functions:

15. Compare the 2 microscopes as to: 1) can living cells be observed?2) which can provide the greater magnification? 3)which can reveal the greater detail of the specimen? 4) what are the 2 basic types of the electron microscope-Hint…think, specimens can be thin sections or entire specimens? How else can you compare them? Are there any other interesting microscopes?

16. Just what distinguishes eukaryotic cells from the prokaryotes? What distinguishes the eukaryotic plant cell from the animal cell?

17. Can you state the cell theory? Think about it…Cells are ? And make up ? And cells come from ? What researchers contributed discoveries about cells?
