"Water Fearing" 

• Hydrophobic
• Hydrophilic 
• Hydroelectric 
• Hydroloric

The ability to allow only certain molecules into or out of the cell.

• Semipermeability

• Permeability

• Impermeability

• Unpermeability

Which image correctly shows the way phospholipids arrange themselves in the cell (plasma) membrane?

• 
• 
• 
• 

The model that describes the current understanding of the cell (plasma) membrane structure is

• fluidity model

• fluid mosaic model

• semi-permeable model

• flexible mixture model

Proteins that make up the cell (plasma) membrane

• are only found on the outer side of the phospholipid bilayer

• are able to provide a passageway for certain substance to pass through the membrane

• are only found on the inner side of the phospholipid bilayer

• are only found in the middle of the phospholipid bilayer
