FROM SLUGS TO CELLS…. It’s all about balance!  Cells are constantly “trying” to maintain a balance –(a.k.a. HOMEOSTASIS)  Accomplished by 3 factors:

Cellular Transport Unit 5. Passive Transport  Does not use energy 1. Diffusion Movement of particles from an area of higher concentration to an area.

OSMOSIS Osmosis is a form of passive transport where the solvent water molecules move from an area of high water concentration to an area of low water.

Transport Across The Cell Membrane

A simple rule to remember is: Osmosis. Remember, diffusion is…

Effects of Osmosis on Life  Osmosis- diffusion of water through a selectively permeable membrane.  There are 3 types of solutions: Isotonic Hypertonic.

Question of the Day 12-6 How are diffusion and osmosis related?

Diffusion and Osmosis Chapter 3, Section 4 Of your textbook.

Do you want me to diffuse?. TONICITY- REVIEW FROM LAST CLASS, PG Tonicity refers to the strength of solution in relationship to osmosis. 3 terms.

Osmosis: the diffusion of water molecules through a selectively permeable membrane. Water moves from high to low concentration. Is the membrane permeable.

Cell Transport. Diffusion The cytoplasm is a “solution” of many substances in water. Concentration=mass/volume Diffusion is the process by which molecules.

Cells and their environment. Tonicity (root: tonic) Used to describe the environment around the cell. Environment can be: HYPERtonic = more solute HYPOtonic.

Osmosis: Striking a Balance. Maintaining A Balance Cells are surrounded by watery solutions and are filled by watery solutions. Cells are surrounded by.

Elodea cells normally contain about 1% salt and 99% water. Tap water normally contains about 1% salt and 99% water. The salt solution you used contains.

Osmosis is the movement of water across a membrane from a region of high concentration to a region of low concentration. 20 % salt solution 5% salt solution.

Tonicity is a measure of the osmotic pressure (as defined by the water potential of the two solutions) of two solutions separated by a semipermeable membrane.

Hemolysis Naseem AL-Mthray. Hemolysis Hemolysis is the breakage of the red blood cell’s (RBC’s) membrane, causing the release of the hemoglobin and other.

Osmosis Review

1. Hypertonic solutions Plant cells  the central vacuole loses water and the cells shrink causing wilting. Animal cells  shrink (plasmolysis)

2. Hypotonic Solution Plant cells  CV fills with water, plant becomes stiff and rigid, CW keeps the plant from bursting Animal cells  swell, may burst (“LYSIS”)

3. Isotonic solutions Plant cells Equilibrium Animal cells - water moves back and forth – no change – GOOD!!!

PredictPredict what would happen to the cells below…. 1. RBC – hypotonic solution 2. Elodea – isotonic solution 3. Paramecium – hypertonic solution
