Cell Membranes

A phospholipid has 2 parts. What are they called? 

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

Another term for maintaining an internal balance is...

• Equality

• Equential

• Homeostasis

• Balance

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 

A ______________ is composed of a phosphate and glycerol head and 2 fatty acid chain tails. 

• phospholipid 
• Carbohydrate
• Cholesterol 
• Protein 

Which of the following macromolecules is NOT part of the cell membrane?

• Lipids
• Carbohydrates
• Proteins
• Nucleic Acids

What type of transport is this?

• facilitated diffusion
• active transport
• diffusion
• osmosis

What are two types of passive transport?

• endo and exocytosis 
• in a minute and later
• hydrophobic and hydrophillic 
• osmosis and diffusion

In which direction will these molecules diffuse?

• from right to left
• from left to right
• they will not move at all
• they will move in both directions equally

The cell membrane is selectively permeable, which means...

• All materials can enter and leave the cell
• Certain things can enter while others cannot
• The cell manually sorts through all materials
• Only certain cells can interact with the cell.

Which form of active transport is being shown?

• Pinocytosis
• Endocytosis
• Exocytosis
• Osmosis
