Cell Transport 2020

Diffusion and osmosis are both vital to cell function. Diffusion and osmosis are similar in that they are both types of

• protein synthesis

• Passive Transport

• Cellular replication

• Cellular metabolism

Which of the following scenarios represents an example of osmosis?

• Blood vessels transport glucose to cells

• Carbon dioxide waste is eliminated during respiration

• Limp celery becomes crisp in water

• sweating lowers body temperature

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.

• True 
• False 

Molecules using simple diffusion move from 

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