2.6 Facilitated Diffusion & 2.7 Tonicity and Osmoregulation (day 1)

 

Today's Learning Objective(s):

Explain how the structure of a molecule affects its ability to pass through the plasma membrane.

Explain how concentration gradients affect the movement of molecules across membranes.

Explain how osmoregulatory mechanisms contribute to the health and survival of organisms.

Tasks:

1	PhET Simulation Does the concentration of one particle affect the other? How can we show this in the simulator?    Simulation Link
2	Examples of Facilitated Diffusion What are examples of facilitated diffusion? You are to use resources to find examples and provide a description of each. You will share what they found out.   AI ✅ Idea Generation
3	Demonstration – Water Potential What is the potential of water? Let’s explore with Orbeez and a graduated cylinder.
4	Teacher notes: Tonicity and Osmoregulation The teacher presents an explanation of the movement of water into and out of cells via membranes and aquaporins.

2.5 Membrane Transport

 

@ExplainingWhy

Today's Learning Objective(s):

Describe the mechanisms that organisms use to maintain solute and water balance.

Describe the mechanisms that organisms use to transport large molecules across the plasma membrane.

Tasks:

1	Animated Gif Review the animations below. What are the differences between passive and active forms of transport? What are the differences between diffusion and facilitated diffusion?
2	Venn Diagram – Active v. Passive Transport While using the textbook, you are to compare and contrast the two types of transport. Then, let’s hear your ideas. Textbook: 5.2 Passive Transport    5.3 Active Transport
3	Video Membrane Transport Let’s pause a moment and watch the video.   Link    Why do particles move from higher concentration to lower concentration?  Other than using a protein pump, how else are materials moved passed the plasma membranes of cells?
4	Teacher Notes: Membrane Transport Let’s look at some slides and go over the types of transport you added to the Venn diagram.
5	Checkpoint > Membrane Permeability Use the Google Classroom assignment to show what you’ve learned about the plasma membrane structure and function.   Classwork   👓 Check your work. 📝 Make corrections to the form. 🔄️ Unlimited attempts at item correction

2.4 Membrane Permeability

 

Today's Learning Objective(s):

Explain how the structure of biological membranes influences selective permeability.

Describe the role of the cell wall in maintaining cell structure and function.

 

Tasks:

1	Simulation Access the simulation.   What impact does the membrane have on these particles? What impact might this phenomenon have on the human body?
2	Movement of Particles Across the Membrane Generate a list of things cells need and need to expel. Think of all the molecules that you’ve learned. How about those ions and minerals cells need?   Then, using internet resources, you are to determine how those particles, molecules, and ions get passed the plasma membrane. Newsprint
3	Cell Defense Simulator  Use Bioman to explore the cell defense simulator. Link    How do the particles in the simulator act as expected?   Is there any part of the simulation that acts in a different manner?
4	Teacher notes: Membrane Permeability Let’s look at some slides and go over the things you saw in the simulators and looked up online.
5	Assessment Qs  -  Plasma  Membrane Use the Google Classroom assignment to show what you’ve learned about the plasma membrane structure and function.   Classwork
