What is something that prokaryotic and eukaryotic cells have in common?

• They have a nucleus. 
• They are multi-cellular. 
• They have DNA. 
• They have organelles that are membrane-bound.

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 

Which of the following is the best example of osmosis? 

• NA/K Pump 
• Water moving though the cell membrane 
• Kidneys 
• Photosynthesis 

What is an isotonic solution?

• When solutions are in equilibrium 
• When the solution has more solute 
• When the solution has less solute 
• Has a greater pressure 

The nuclear envelope encloses the nucleus and its contents.

• True 
• False 

Molecules using simple diffusion move from 

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

This picture represents what type of cell transport?

• endocytosis
• exocytosis
• osmosis
• passive transport

Movement of particles from high to low concentration. 

• Passive Transport
• Active Transport
