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
