What kind of transport does not require energy?

• Active 
• Vacuole 
• Passive 
• Na/K Pump 

What is facilitated diffusion?

• Transport that uses proteins to help move molecules across the membrane. 
• Movements of substances through a membrane. 
• When molecules spread from High to Low concentration on their own. 
• When pressure pushes something through a membrane. 

What macromolecules help to make the cell membrane? 

• Proteins 
• Carbohydrates 
• Phospholipids 
• All of the above 

All of the following statements are true about prokaryotic cells EXCEPT 

• No nucleus 
• They are simple and small 
• Have a cell wall 
• Have organelles 

Movement of materials through a vesicle into the cell that requires energy is 

• exocytosis
• endocytosis 
• osmosis 
• simple diffusion 

What are the 2 parts of a phospholipid? 

• Hydrophobic head, hydrophilic tails 
• Hydrophobic heads, hydrophobic tails 
• Hydrophilic heads, hydrophobic tails 
• Hydrophilic heads, hydrophilic tails 

Molecules using simple diffusion move from 

• high to low concentrations 
• low to high concentrations 
• no concentrations  
• both concentrations  

Osmosis is the movement of... 

• salt 
• sugar 
• water 
• none of these
