Diffusion and Osmosis. Diffusion is the movement of molecules from a high concentration to a low concentration. Many molecules diffuse across cell membranes.

Chapter 3. Passive Transport  Diffusion – molecules move spontaneously (no energy used) from an area of high concentration to an area of low concentration.

Diffusion The movement of molecules from an area of high concentration to an area of low. concentration.

Unit 4, Lesson 2 Passive Transport. Passive Transport is the movement of molecules across a membrane that does not require energy No energy is required.

Materials move across membranes because of concentration differences.

PASSIVE TRANSPORT One way cells maintain homeostasis is by controlling the movement of substances across their cell membrane. Cells want to reach “equilibrium”.

Cellular Transport: movement of materials in and out of a cell  Homeostasis: combination of two words  Homeo = same  Stasis = steady  Homeostasis:

Hypotonic, Isotonic, & Hypertonic. A solute is… the substance dissolved in a given solution.solution.

How cells move things in and out CELL TRANSPORT How cells move things in and out

Solutions __________: combination of solute and solvent (Solution= solute + solvent) _________: substance being dissolved (ex. Salt) ____________: substance doing the dissolving (ex. Water) _____________: amount of solute in a solvent (difference in concentrations = “concentration gradient”)

How substances move _________________: movement across a cell membrane that does NOT require energy ENERGY

Types of Passive Transport ____________: Molecules move from areas of HIGH concentration to LOW concentration to create an equilibrium ____________: Diffusion of water in and out of the cell to create an equilibrium _________________: Uses carrier proteins to transport substances to create an equilibrium (Fig. 4- pg. 80)

Types of Solutions Isotonic: “iso”- _________ Concentration is the _______ inside and outside of the cell (Water moves in/out at _________ rate)

Type of Solutions Hypotonic: “hypo”- _________ Concentration is ___________outside the cell than inside (Water goes ______ the cell faster than ____)

Type of Solutions Hypertonic: “hyper”- ____________ Concentration is _________ outside the cell than inside (Water moves ________ of the cell faster than _______)

Type of Solutions- Video

How substances move __________________: requires energy to move substances in/out of the cells WHY? ____________________________ Used to transport substances: ____________________ _____________________: carry ________ a cell _____________________: carry ________ of a cell
