Cell Membrane

Define plasma membrane

• lipid that helps minimize effects of temperature

• only on the outer surface of the plasma membrane and are attached to proteins or lipids; form distinctive cellular markers

• flexible boundary of a cell that separates a cell from its surroundings

• may extend partway into the plasma membrane, cross the membrane entirely, or be loosely attached to its inside or outside face

What is the "big idea" of the fluid mosaic model of plasma membranes?

• the plasma membrane creates a specialized FLUID that looks like a MOSAIC.

• the plasma membrane is a MOSAIC.

• the fluid mosaic model is NOT related to the plasma membrane.

• a plasma membrane is a MOSAIC of components that move FREELY and FLUIDLY.

What does "hydrophobic" mean?

• water loving, associates with water

• water fearing, does not associate with water

• a world war II submarine

• an example would be solutes like sugar or salt

The function of the plasma membrane is....

• to regulate what enters and leaves the cell.
• fight bacteria and viruses that enter the cell.
• provide rigid support and protection to the cell.
• make sure each cell can move
