1. Warm up #5 Identify 3 differences between plant and animal cells
Describe 2 characteristics about the cell membrane
Why is the cell membrane referred to as selectively permeable?

2. Warm up #6 Which type of transport is with the diffusion of water?
Identify which type of transport uses a protein pump and requires ATP?
Differentiate between diffusion and active transport (go for at least 2 differences)

3. transportation

5. Nature always seeks balance

6. Diffusion
Solutes-red dots, water/outside area is solvent Concentration-mass per volume (m/v) of solute in a solvent

7. Diffusion

8. Equilibrium

9. Equilibrium

10. Osmosis
The diffusion of water through a selectively permeable membrane

12. Isotonic-when the concentration of water is equal to the concentration of solute

13. Hypertonic-solution has higher solute concentration than the cell Hypotonic-solution has lower solute concentration than the cell

16. Facilitated Diffusion
Cell membrane proteins help or ‘facilitate’ the diffusion of molecules across membrane -these molecules are too big or do not have the right charge to diffuse through membrane so they must go through protein channels

17. Active Transport
Requires energy, goes AGAINST concentration gradient -carried out by carrier proteins or Pumps

19. Endocytosis
Endo-means ‘in’ The process of taking materials into the cell by foldings at cell membrane

20. Phagocytosis
Extension of cytoplasm surrounds a particle & packages it within a food vacuole

21. Pinocytosis
Cells also take up liquid. Tiny pockets form along cell membrane, filled w/ liquid, then pinch off to form vacuoles inside cell

23. Exocytosis
Exo-to exit When cells release large amounts of material from the cell Vacuole fuses with cell membrane, forces content out of the cell

25. Cell Specialization
Process by which cells develop (differentiate) to perform specific tasks
