1 Movement of particles across the cell membrane without using energy
Section 4 Cellular Structure and Function Cellular Transport Passive Transport Movement of particles across the cell membrane without using energy Three Modes of Passive Transport Diffusion Facilitated Diffusion Osmosis

2 Section 4 Cellular Structure and Function Cellular Transport Diffusion Movement of particles from an area of high concentration to an area of lower concentration

3 Diffusion is controlled by
Section 4 Cellular Structure and Function Cellular Transport Diffusion is controlled by Temperature Pressure Concentration Dynamic Equilibrium Reached when diffusion of material into the cell equals diffusion of material out of the cell Molecules continue to move, but the overall concentration remains the same.

4 Diffusion in a Cell Cellular Transport Cellular Structure and Function
Section 4 Cellular Structure and Function Cellular Transport Diffusion in a Cell

5 Facilitated Diffusion
Section 4 Cellular Structure and Function Cellular Transport Facilitated Diffusion Movement of materials across the plasma membrane using proteins

6 Channel Proteins Carrier Proteins Cellular Transport
Section 4 Cellular Structure and Function Cellular Transport Channel Proteins Carrier Proteins

7 Diffusion of water across a selectively permeable membrane
Section 4 Cellular Structure and Function Cellular Transport Osmosis Diffusion of water across a selectively permeable membrane Three Types of Solutions Isotonic Hypotonic Hypertonic

8 Section 4 Cellular Structure and Function Cellular Transport Isotonic Solution Water and dissolved substances diffuse into and out of the cell at the same rate. Plant Cell

9 Solute concentration is higher inside the cell.
Section 4 Cellular Structure and Function Cellular Transport Hypotonic Solution Solute concentration is higher inside the cell. Water diffuses into the cell. Plant Cell

10 Solute concentration is higher outside the cell.
Section 4 Cellular Structure and Function Cellular Transport Hypertonic Solution Solute concentration is higher outside the cell. Water diffuses out of the cell. Plant Cell
