Launch Objective: I can differentiate between osmosis and diffusion.

The Cell Membrane Composed of a lipid bi-layer and transport proteins embedded in the bi-layer. Has receptors on its surface which allows the cells to recognize hormones and communicate with other cells. Selectively permeable membrane- allows some molecules to pass, but not others. Objective: I can differentiate between osmosis and diffusion.

Cell Membrane Structure Identify the lipid bi-layer, proteins, and receptors. Objective: I can differentiate between osmosis and diffusion.

What materials move across the cell membrane? • Water, nutrients, gases and wastes constantly move in two way traffic across a cell membrane. • Some molecules pass “freely” while others move only if the cell expends energy. Objective: I can differentiate between osmosis and diffusion.

There are 2 types of transport across the cell membrane: Passive transport - a cell process in which needed materials enter the cell and waste leaves the cell. Requires NO energy (ATP) by the cells. Active transport – a cell process by which materials move into or out of a cell, This process requires energy (ATP). Objective: I can differentiate between osmosis and diffusion.

Transport Hill Active Transport ATP Required Molecules move from an area of low to high concentration LOW HIGH Passive Transport No ATP Required Diffusion/Osmosis Molecules move from an area of high concentration to low concentration. LOW

Passive Transport There are 2 types of passive transport: Diffusion (movement of molecules) Osmosis (movement of water molecules only) The goal of both diffusion and osmosis (passive transport) is to reach EQUILIBRIUM within the cell Equilibrium is a condition in which the movement in one direction is equal to the movement in another direction Objective: I can differentiate between osmosis and diffusion.

Examples of diffusion Have you ever walked into your house and smelled someone cooking? Have you ever put die in a cup of water or milk in a cup of coffee or tea? Have you ever squirted a spray? Objective: I can differentiate between osmosis and diffusion.

Diffusion Demo Diffusion of Liquids Objective: I can differentiate between osmosis and diffusion.

The movement of molecules from an area of higher concentration to lower concentration across the cell membrane.

When there is no net movement of molecules into or out of the cell, it is said to be in equilibrium.

Diffusion – the process in which materials move from an area of HIGH concentration to an area of LOW concentration (down the concentration gradient) Concentration gradient- difference in concentration between 2 regions. Molecules in motion “bounce” off each other and spread out in all directions until there is an equal distribution of molecules in the area. Objective: I can differentiate between osmosis and diffusion.

What materials diffuse into and out of the cell and why? Materials needed to maintain homeostasis diffuse into and out of the cell. The size and charge of the material usually determines if the materials will be allowed across the membrane using diffusion. Materials that enter the cell include: oxygen, glucose, and digested nutrients (amino acids, fatty acids) Waste materials that leave the cell include: carbon dioxide, urea Objective: I can differentiate between osmosis and diffusion.

Passive Transport: 1. The cell membrane controls what enters and leaves the cell. 2. Passive transport is the movement of materials into or out of the cell which does not require energy (ATP).

Passive Transport: Diffusion is one type of passive transport in which materials move from higher concentration to lower concentration. Only small materials diffuse easily across the cell membrane.

Think about it: Can you think of anything that will expand when you put it in water? Objective: I can differentiate between osmosis and diffusion.

What about water? ? ? OSMOSIS Osmosis is the diffusion of water across a membrane. Osmosis is a type of passive transport in which water flows from a region of HIGH to LOW concentration. requires NO ATP (energy)

THINK ABOUT IT When you are thirsty, you may drink water to quench your thirst. How does drinking water help?

Osmosis in Different Solutions • Isotonic solutions • Concentration outside of the cell EQUALS the concentration inside of the cell. • No net movement of water 59

Cell in Isotonic Solution 10% Na. CL 90% H 2 O ENVIRONMENT CELL 10% Na. CL 90% H 2 O What is the direction of water movement? The cell is at ________. 60

Hypotonic Solutions When cells are placed in pure (100%) water, water enters the cell by osmosis and causes the cell to swell and eventually burst and is permanently destroyed.

Cell in Hypotonic Solution 10% Na. CL 90% H 2 O CELL 20% Na. CL 80% H 2 O What is the direction of water movement? IN to the CELL 62

Hypertonic Solutions When cells are placed in salt or sugar solutions, water leaves the cell by osmosis and the cell shrinks and gets smaller. This process may be reversed.

Cell in Hypertonic Solution 15% Na. CL 85% H 2 O ENVIRONMENT CELL 5% Na. CL 95% H 2 O OUT of the CELL What is the direction of water movement? 64

When cells are placed in pure water, they will swell and burst; When placed in salt water, they will shrink. Cells in pure water will swell and burst A plant cell will swell but not burst. A cell in salt water gets shrinks! Plant cells have cell wall The inside of cell will shrink, but the cell wall will not.

Three Relationships of Solutions Which beaker demonstrates the changes of a cell in… Salt water? Fresh water?

Osmosis and cell structure Pure water -------normal-------salt solution Burst cells------normal cells-------cell shrinkage

Osmosis in the plant cell: The plant cell will swell when placed in pure water, but will not burst due to the cell wall. When placed in salt water, only the inside of the cell and cell membrane will shrink, the cell wall remains the same. Cell membrane Cell wall cytoplasm

How is active transport different from diffusion? Cells must move materials against a concentration gradient. It requires ATP (cellular energy) • Protein pumps transport molecules across the membrane.

Active Transport • Requires energy or ATP • Moves materials from LOW to HIGH concentration • AGAINST concentration gradient 92

Active transport: uses ATP When materials move from low to high concentrations, energy is needed to move these materials against the normal directional flow!

Moving the “BIG stuff” Endocytosis: the movement of a substance INTO a cell by a vesicle (package) Exocytosis: the movement of a substance OUT OF a cell by a vesicle

Active Transport Pinocytosis: plasma membrane “pinches in” to permit entry of molecules too large to diffuse through “cell drinking”

Active Transport Phagocytosis: cytoplasm of cell surrounds and engulfs particle (ex: white blood cells ingest germs!) “cell eating”

Active transport • Exocytosis – pushes particles out of cell; opposite of endocytosis
