Group Activity Task: Design a system where one type of animal can be transported between two sealed compartments. One compartment will contain many types of animals that are relatively the same size. For example, mice, rats, squirrels, chipmunks etc. The task at hand is for students to design a system for only mice to be able to be transported into the second compartment where there is food.

Learning Intention !  I can explain the structure of a plasma membrane

Cell Membranes: Fluid Mosaic Model

Cell Membranes: Fluid Mosaic Model

Hydrophilic and Hydrophobic Regions

Fluid Bilayer and Bilayer Vesicle

Take Away Task !  Create a graphic organizer to explain the structure of the

plasma membrane.

!  We will add to this graphic organizer throughout the unit.

!  Components to include: phospholipids, proteins, carbohydrate chains, and cholesterol.

!  For next class, complete the phospholipid section. !  Structure of phospholipid (included the chemical formula) !  Draw a diagram of the cell membrane !  Properties of the phosphate head and fatty acid tails !  Why is it called a bilayer? !  Describe why the phospholipid bilayer creates a barrier for

polar molecules?
