cells and cell transport

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 

All of the following statements are true about prokaryotic cells EXCEPT 

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

Which of the following is the best example of osmosis? 

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

What are the 2 parts of a phospholipid? 

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

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 

Which of the following is correct about the Golgi? 

• Digests waste materials 
• Protection and Support 
• Modifies and packages molecules 
• cellular movement
