Describes the arrangement of the cell membrane as semi-fluid and made of a range of molecules.

___________ play a role in cellular recognition and immune response. They act like an ID tag for the cell.

___________ strengthens and stabilizes the cell membrane. Increasing stability and increasing fluidity dependant on environmental conditions.

The term to describe a cell membrane that allows some substances to pass, but not others

This is the part of the bilayer that is attracted to water (because it is polar)

This is the part of the bilayer that repulses water molecules (because it is non-polar)

Means "water lovings" Describes the heads (circle portion) of the phospholipids

Means "water fearing". Describes the tails of the phospholipids

This component of the cell membrane allows the passive transport of specific molecules, working like a tube across the phospholipid bilayer.

The cell membrane is also called the __________ __________.

What is a type of lipid in the cell membrane that makes the bilayer more fluid, flexible and at the same time stable?

What is the name of a protein that is embedded through the entire cell membrane. These include the channel proteins and protein pumps which allows for movement of larger molecules in and out of the cell.

These proteins are only found on the outside or inside surface of the cell membrane.

Identify what part of the cell membrane that is represented by letter B.

Identify what part of the cell membrane that is represented by letter A.

Analyze the cell membrane diagram. Identify the letter that is considered hydrophobic.
