Cell membrane
Cell wall
Ribosomes

5. What is the increasing order of levels of orginazation
Cell- tissue- organ- system- organism

6. What advantage do multicellular organisms have over unicellular organisms?
Their cells are specialized for different functions

7. What is the purpose of cilia and flagella?
Movement (mobility, motility)

8. What is the endosymbiotic Theory?
Prokaryotic cell engulfs other prokaryotic cell eventually becoming a primitive plant cell or animal cell

9. 2. Passive Transport

10. Why is this type of transport celled “passive”?
No energy is used

11. What is the diffusion of water called?
osmosis

12. Identify hypotonic, Hypertonic, Isotonic:
More h2o less solute- hypotonic
Less h20 more solute- hypertonic
Same h20 and solute- isotonic

13. What type of diffusion uses carrier proteins?
Facilitated diffusion

14. Which direction do molecules move across the concentration gradient in this type of transport?
High to low concentrations

15. What is a semipermeable membrane?
Allows certain materials to pass through and others cant

16. How does the size of molecules affect movement across a membrane?
Smaller things move accros

17. 3. Active transport

18. Why is this type of transport called “active” ?
Uses energy

19. What are examples of active transport?
Phagocytosis
Pinocytosis
Exocytosis
Sodium/ potassium pump

20. Which direction do molecules move across the concentration gradient in this type of transport?
Low to high

21. Why is the sodium potassium pump considered active transport?
Uses energy to move from low concentrations to high concentrations

22. 4. Photosynthesis

23. In what organelle does this occur?

32. If a cell runs out of oxygen what type of respiration will it revert to?
anaerobic

33. What is the purpose of the Electron Transport chain?
ATP for energy is made to be utilized by the cell?
