Cell movement

Active transport occurs when _______ is used to move substances through a membrane.

• Osmosis
• Energy
• Diffusion
• Chlorophyll

The passive transport of water through a membrane is ______.

• Osmosis
• Fermentation
• Equilibrium
• Active transport

What is the main difference between active transport and passive transport?

• Active transport transports in the cell and passive in the cytoplasm
• Passive does NOT use energy ans active does
• Active moves from high to low and passive is low to high
• Passive moves large molecules and active forms vesicles

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 

Active transport does not require energy.

• True 
• False 

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
