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.

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?

Teacher notes: Membrane Permeability

Let’s look at some slides and go over the things you saw in the simulators and looked up online.
