Table 10

1. You pour milk into a cup of hot coffee. What will the coffee look like after 3 minutes?

2. What is the name of the organelle that completely surrounds the cell (all cells have

it!)?

Warm up (3 minutes) 1. Pick up a warm up

2. Pick up the student work from the front table

3. Pick up your binder in the filing cabinet

4. Complete the warm up

5. Secure all handouts in your binder

This stopwatch is timing how long it takes you to get ready. It will stop after everyone

- has completed a warm up - has their binder in front of them - has today’s work - is sitting in their assigned seat - has given 3 seconds of silence.

Your class will gain points based on how quickly this happens.

Topic 1.11.1

Cell Transport, p. 40

Today’s Plan:

1. Warm Up (3 min)

2. Turn & Talk (3 min)

3. Note-taking

4. Cell Transport Scenarios

5. Exit Slip (5 min)

Today’s Objective:

Describe active and passive

transport; differentiate between

diffusion and osmosis.

FOCUS QUESTION: How do materials pass into

and out of cells?

1. You pour milk into a cup of hot coffee. What will the coffee look like after 3 minutes?

1. What is the name of the organelle that completely surrounds the cell (all cells have

it!)?

Warm Up Review

The cell membrane

1. Cell Transport

Materials within a cell need to be able to move through the cell in order to complete the functions of life.

2. There are 2 mechanisms that cells used to transport materials: a. Passive Transport b. Active Transport

3. Active Transport is the movement of molecules in or out of the cell that requires energy

4. There are 2 forms of Active Transport: a. Endocytosis- molecules move into a cell when the cell membrane creates a pouch and pinches off.

b. Exocytosis- molecules move out of a cell when a waste vacuole attaches to the cell membrane and releases the waste.

5. Passive Transport is the movement of substances into or out of a cell without the use of energy. There are 2 forms of Passive Transport: a. Diffusion

b. Osmosis

Diffusion Video

7. What happened to the sugar when it was dropped into the water?

8. The movement of molecules from an area of their high concentration to an area of their low concentration is called diffusion.

9. What do you think the “concentration” of a substance is?

Video #2: Watch the video about osmosis on the next slide and answer questions #10-11

10. Why couldn’t the urea molecule pass through the membrane? 11. When water molecules move from an area of their higher concentration to an area of their lower concentration across a membrane, this is called osmosis.

It was too large to pass through

12. Why is the sugar cube NOT an example of osmosis? Osmosis only happens with water molecules.

13. Plasma membranes are selectively permeable which means that certain materials can pass into and out of the cell, but other materials cannot.

Diffusion, Osmosis, or Active Transport? #11-15 Read each scenario and decide whether it is an example of diffusion, osmosis, or active transport.

Example Scenario: The summer has been very dry. The plants on the green roof are starting to wilt from lack of water. One evening, a summer thunderstorm strikes, and it rains heavily. The plant roots take in the rainwater.

Diffusion, Osmosis, or Active Transport? Read each scenario and decide whether it is an example of diffusion or osmosis. Support your choice with an explanation.

Exit Slip (5 min) 1. Return to your assigned seat

2. Complete the exit slip

3. Clean up your workstation

4. Secure all handouts in your binder

5. Put your binder away.

1. What is the difference between diffusion and osmosis?

1. True or False: In diffusion, substances move from low concentration to high concentration. EXPLAIN YOUR ANSWER!
