3 LT 3 Cell Transport

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. 

Which of the following is the best example of osmosis? 

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

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

• exocytosis
• endocytosis 
• osmosis 
• simple diffusion 

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

• hypertonic solution
• isotonic solution
• silly solution

If the sodium concentration inside a cell is greater than outside the cell, how can a cell take in more sodium?

• osmosis
• diffusion
• active transport
• passive transport

if you put a plant in salt water it will ...

• swell because water diffuses into the cells
• swell because water diffuses out of the cell
• shrivel because water diffuses out of the cell
