• mRNA is used to form protein
• 3. vesicle from RER to Golgi
• 4. Golgi
• Packaged for shipping
• 5. vesicle to cell membrane for release

Chapter 3 Test Review
11
Chapter 3 Test Review

• Nucleus
• Parts
• Plant/animal
• Essays
• Endosymbiont hypothesis
• What is the hypothesis?
• What organelles fit the hypothesis?
• Evidence for the hypothesis
• Cell as a factory analogy
• Choose 6 organelles and explain how each would
  serve as a factory part

12
Passive Transport

• The movement of molecules through a membrane
  without any energy from the cell.
• DIFFUSION
• Molecules will move from areas of high
  concentration to areas of low concentration
• Equilibrium Concentration is equal throughout a
  space.
• End of diffusion

14
Diffusion in cells

• Into or out of a cell
• Through lipid bilayer
• This is how water, oxygen, and carbon dioxide
  pass through the cell membrane
• Go with the concentration gradient
• think hill

15
Selectively permeable membranes

• Allows small polar or nonpolar particles through
• larger or polar particles do not pass

16
Where are the polar and nonpolar areas?
