1. MOVING MATERIALS INTO AND OUT OF CELLS

2. MATERIAL MOVEMENT PASSIVE TRANSPORT ACTIVE TRANSPORT

3. PASSIVE TRANSPORT DIFFUSIONOSMOSIS

4. PASSIVE TRANSPORT WITHOUT USING ENERGY WITHOUT USING ENERGY DOWN HILL DOWN HILL

5. DIFFUSION MOVEMENT FROM AN AREA OF HIGHER TO A LOWER CONCENTRATION MOVEMENT FROM AN AREA OF HIGHER TO A LOWER CONCENTRATION Uses O energy Uses O energy thru a membrane thru a membrane

6. DIFFUSION (CONTINUED)

7. WHAT IS A SOLUTION? WHAT IS A SOLUTION? WHAT IS THE SOLUTE? WHAT IS THE SOLUTE? WHAT IS THE SOLVENT? WHAT IS THE SOLVENT?

8. SOLUTION A mixture that is consistent throughout A mixture that is consistent throughout Example salt water Example salt water

9. SOLUTE A SUBSTANCE THAT DISSOLVES A SUBSTANCE THAT DISSOLVES IN A SOLUTION –Example: SALT in Salt Water

10. SOLVENT A Substance in which a solute dissolves in a solution A Substance in which a solute dissolves in a solution Example: the WATER in a solution Example: the WATER in a solution

11. OSMOSIS MOVEMENT OF WATER ACROSS A MEMBRANE

12. OSMOSIS (CONTINUED) SALT SUCKS SALT SUCKS

13. OSMOSIS (CONTINUED) HYPOTONIC SOLUTION HYPOTONIC SOLUTION –WATER CONCENTRATION lower – and –SALT CONCENTRATION IS higher –WATER WILL MOVE INTO THE CELL

14. OSMOSIS (CONTINUED) HYPERTONIC SOLUTION HYPERTONIC SOLUTION –WATER CONCENTRATION higher – AND – SALT CONCENTRATION IS lower –WATER WILL MOVE OUT OF THE CELL

15. OSMOSIS (CONTINUED) ISOTONIC SOLUTION ISOTONIC SOLUTION –WATER CONCENTRATION SAME ON BOTH SIDES OF THE MEMBRANE

16. OSMOSIS (CONTINUED) TURGID = SWOLLEN LYSED = BREAK FLACCID = NOT FIRM SHRINK

17. FACILITATED DIFFUSION Materials too large to sift thru the heads and tails of the membrane. Materials too large to sift thru the heads and tails of the membrane. Needs to go in thru the Intrinsic protein channels. Needs to go in thru the Intrinsic protein channels. Still uses NO energy Still uses NO energy It is still diffusion It is still diffusion

18. ACTIVE TRANSPORT

19. ENERGY IS USED TO MOVE MATERIAL ACROSS THE MEMBRANE ENERGY IS USED TO MOVE MATERIAL ACROSS THE MEMBRANE USUALLY FROM AREA OF LESSER CONCENTRATION TO AREA OF GREAT CONCENTRATION USUALLY FROM AREA OF LESSER CONCENTRATION TO AREA OF GREAT CONCENTRATION UP HILL UP HILL

20. ACTIVE TRANSPORT (CONTINUED) EXAMPLE: SODIUM-POTASSIUM PUMP EXAMPLE: SODIUM-POTASSIUM PUMP MOVEMENT GLUCOSE INTO CELL: TYPCIALLY, CONCENTRATION WILL BE GREATER IN CELL MOVEMENT GLUCOSE INTO CELL: TYPCIALLY, CONCENTRATION WILL BE GREATER IN CELL

21. Na + MOVED AGAINST CONCENTRATION GRADIENT

22. ENDOCYTOSIS MOVEMENT OF TAKING MATERIAL INTO THE CELL

23. Phagocytosis Cell Eating Cell Eating Taking FOOD into the cell Taking FOOD into the cell

24. Pinocystosis Cell Drinking Cell Drinking Taking liquid in the cell Taking liquid in the cell

25. EXOCYTOSIS MOVEMENT OF MOVEMENT OF TAKING TAKING MATERIAL OUT OF THE CELL MATERIAL OUT OF THE CELL
