• Hydrophobic (hate water)
• Hydrophilic (love water)
• Long
• Short

Hydrophobic = 

• Water loving
• Water hating
• Made of hydrogen
• Made of water

Which of the following molecules make up the basic structure of a cell membrane?

• waxes
• steroids
• fatty acids
• phospholipids

A phospholipid has 2 parts. What are they called? 

• Hydrophilic Head, Hydrophobic Tail 
• Hydrophobic Head, Hydrophilic Tail 

This forms a boundary between the inside of the cell and the outside of the cell. 

• Cell Membrane
• Lipid Cleric Layer
• Membrane Gate
• Protein Receptors
