Parts of the Cell Theory
Differences between prokaryotes and eukaryotes
Cell Organelles and Functions
Differences between Plant and Animal Cells
Know plant and animal cell diagrams on page 175 (Figure 7-6)
Terms:
o Concentration
o Solute
o Solution
o Equilibrium
o Diffusion
o Selectively permeable
o Osmosis
o Hypertonic
o Hypotonic
o Isotonic (Figure 7-16 p.186)
o Passive transport
o Facilitated diffusion
o Active transport
o Endocytosis (phagocytosis & pinocytosis)
o Exocytosis
Compare and contrast diffusion and osmosis
Explain the difference between endocytosis and exocytosis.
What two organelles are involved in endocytosis?
What is the role of adenosine triphosphate (ATP) in active transport?
A Paramecium’s contractile vacuole pumps water out of the cell. Is this active or passive transport?
Describe the role of carrier proteins in active transport.
Differences between unicellular vs. multicellular
Specialization in plant and animal cells
Levels of organization
Labs:
o Appendix D parts/function of microscope
o What happened to the letter “e” under the microscope?
o What happens to the image as you move the slide to the right? To the left? Away from you?
o What is the magnification of the eye piece on your microscope? Low power? Medium power?
High power?
o How do you calculate the total magnification?
o What structures could you see in the Elodea? In the cheek cell?
o What color indicates that starch is present when mixed with iodine?
o Did starch diffuse out of the dialysis tubing into the beaker?
o Which substance do you think has bigger molecules, starch or iodine? How do you know?
o How does the dialysis tubing work like a cell membrane?
o Which egg gained water? Which egg lost water?
o Explain why there were changes in the mass of the eggs, either a loss or gain.
o Using the terms isotonic, hypotonic, and hypertonic explain the changes in mass of the two eggs.
Something to think about??
 After a long bath your finger tips look all wrinkled. Why?
 Some people claim to “learn by osmosis” – does this make sense?
