Section 3 Cellular Structure and Function Structures and Organelles Cilia Short, numerous projections that look like hairs Flagella Longer and less numerous than cilia Create movement with a whiplike motion

8 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

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

10 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.

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

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

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

14 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

15 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

16 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

17 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

18 Active Transport Using Carrier Proteins

19 Types of Active Transport Pumps
Section 4 Cellular Structure and Function Cellular Transport Types of Active Transport Pumps Na+/K+ ATPase pump Moves three Na+ ions out of the cell and two K+ ions into the cell

20 Process by which the cell surrounds and takes particles into the cell
