1. Movement in cells Active Transport and Passive Transport,
Transport is the way a cell moves things through a membrane.

2. Cell Membrane (Transport)
Cell Membrane and Cell Wall:
ALL cells have a cell membrane
Cell Membrane
protein channel
protein pump
Layer 1
Layer 2
SOME cells have cell membranes and cell walls – ex: plants,
Cell Membrane
Cell Wall
Only in Plant Cells!

3. Function of the Cell Membrane:
The cell membrane separates the cell from its environment (what surrounds the cell)
The cell membrane is the “Gatekeeper” of the cell—it controls the flow of materials into and out of cell.
Cell membrane helps cells maintain balance in the cell

4. Active Transport vs Passive Transport
ENERGY REQUIRED
You might need a push!
Passive Transport-
NO ENERGY REQUIRED
Smooth sailing all the way

6. (move from crowded area to less crowded area)
Passive Transport
A process that does not require energy to move molecules through a membrane.
(move from crowded area to less crowded area)
Types of Passive Transport
Diffusion
Osmosis
Diffusion and Osmosis
Brainpop- Passive Transport

7. Diffusion is when molecules move from a more crowded to a less crowded area.
These particles move from an area of high concentration ( a lot) to an area of low concentration (a little).

inside of cell

9. Osmosis is the passive transport of water (**No energy required)
Semi-permeable (not everything can go through it ) membrane is permeable to water, but not to sugar

11. How the Sodium Pumps work

12. Active Transport
Energy is required to move materials through a cell membrane.
A “pump” in the cell is used to help move materials.
Proteins that work as pumps are called protein pumps.

17. Photosynthesis light+ to put together=photo/synthesis
The Photosynthesis Song
T he process by which plants produce their own food and energy, using only the natural source of light and water.
Plants take in CARBON DIOXIDE and produce OXYGEN- which animals breathe!
Carbon dioxide + water +sunlight -> glucose(food ) + oxygen

19. Respiration The AMOEBA SISTERS CELLULAR REPIRATION AMOEBA SISTERS WS
Respiration is a process by which cells get energy stored from food.
Respiration happens in ALL living things.
Oxygen + Glucose --> Carbon Dioxide + Water+ Energy
