1. Warm-Up
Compare the function of the cell wall and the cell membrane in plant and animal cells.
Describe the characteristics and role of the nucleus.
What are two ways cells can differ?
What organelles are found in the cytoplasm and what are their functions?

2. The Cell in its Environment
(Set up for Cornell Notes)
How big is a cell?

3. CELL MEMBRANE
Selectively Permeable: Some substances can go through it while others cannot.

4. DIFFUSION
Molecules move from an area of higher concentration to an area of lower concentration.

5. Diffusion of water through a selectively permeable membrane.
OSMOSIS
Diffusion of water through a selectively permeable membrane.

6. Cornell Notes Selectively permeable Diffusion Osmosis
Some substances can pass through the membrane while others cannot.
Molecules move from an area of higher concentration to an area of lower concentration.
The diffusion of water molecules through a selectively permeable membrane.

7. Movement of materials through a cell membrane using energy.
ACTIVE TRANSPORT
Movement of materials through a cell membrane using energy.

8. Movement of materials through a cell membrane using energy.
ACTIVE TRANSPORT
Movement of materials through a cell membrane using energy.

9. ACTIVE TRANSPORT
Movement of materials through a cell membrane using energy.

10. ACTIVE TRANSPORT
Movement of materials through a cell membrane using energy.

11. ACTIVE TRANSPORT
Movement of materials through a cell membrane using energy.

12. ACTIVE TRANSPORT
Movement of materials through a cell membrane using energy.

13. ACTIVE TRANSPORT
Movement of materials through a cell membrane using energy.

14. (THE OPPOSITE OF ACTIVE IS PASSIVE TRANSPORT)
Does not require energy to pass particles through the membrane

17. Movement of Materials Active Transport Passive Transport
Movement of materials through a cell membrane using energy.
Does not require energy to pass particles through the membrane

18. Proteins in the cell membrane that carry molecules using energy.
TRANSPORT PROTEINS
Proteins in the cell membrane that carry molecules using energy.

19. A cell can also move materials by engulfing (also uses energy).
