Transport

•Circulation•Movement of materials into and out of cells

Concentration????

Concentration: the relative amount of a given substance contained within a solution or in a particular volume of space

LOW CONCENTRATION

HIGHCONCENTRATION

•Materials move from high low concentration

•NO ENERGY NEEDED

Passive Transport

When does passive transport stop?

•Occurs until concentration becomes EQUAL on both sides(EQUILIBRIUM)

Explain why this diagram represents passive transport.

high

low

Weeee!!!

Explain why this diagram represents passive transport.

HIGH

LOW

+ energy

1. Identify the high and low concentration.

2. Identify the type of transport occurring. Support your answer.

Active Transport•Movement of materials from

LOW HIGH concentration•ENERGY IS NEEDED!

Exit Card…

Compare and contrast passive and active transport by completing one of the following.

Write a paragraph of at least 4 sentences comparing and contrasting passive and active transport. Be sure to use the following terms: particles, energy, high concentration, low concentration.

OR

Compare and contrast passive and active transport by drawing diagrams of each type. Be sure to label the particles, high concentration, low concentration, energy. Draw an arrow showing the movement of the particles.

Identify the type of transport represented in diagrams A and B. Support your answer.

TRUE OR FALSE

1. Respiration is when structures and organs move oxygen into the body and waste gases out of the body.

2. Breathing can help respiration when its waste gases move out of the body.

3. Respiration is the chemical reaction that happens when oxygen delivered to the cells is used to release energy from glucose.

4. So when you breathe out you are using cell respiration.

5. Respiration spreads necessary items into cells that need it.

6. Breathing is the movement of the chest that brings air into the lungs and removes gas.

7. Respiration is the process when CO2 and H2O molecules are carried back to the lungs in the blood.

8. Respiration is when oxygen is being transported to your cells.

9. Cellular respiration is the part of breathing that removes CO2 and H2O molecules.

10. We inhale air containing waste products.

11. Breathing is a voluntary process while respiration is an involuntary process.
