1. AIM: What is the difference between active and passive transport?
DN: What are the two conditions for diffusion? What is the end result of diffusion? Draw a picture illustrating this.
HW: Page 199 #28

2. Do all things get through the cell membrane?
Water Molecules
SELECTIVELY PERMEABLE

3. When will he need energy?
Should I go up the gradient or down the gradient

4. Types of cell transport
Active transport
Energy required
Against concentration gradient
From low to high
Passive transport
No energy required
Down the concentration gradient
From high to low
Diffusion

5. Passive Transport Diffusion = movement of O2 & CO2
Facilitated diffusion = alcohols & glucose (needs membrane protein)
Osmosis = movement of H2O

6. Active Transport
Phagocytosis
Pinocytosis

7. How can you tell? 3 1 2

8. Can you tell the difference?

9. Would you need energy?

10. Active vs. Passive Transport
Active Transport
Passive
Transport
Energy Required
