What are two types of passive transport?

• endo and exocytosis 
• in a minute and later
• hydrophobic and hydrophillic 
• osmosis and diffusion

Special proteins help move particles, but NO energy is needed. This is..

• facilitated diffusion
• exocytosis
• active transport
• equilibrium

When something is 'water fearing' it is....

• Hydrophobic
• Hydrophilic 
• Hydroelectric 
• Hydrochloric

In which direction will these molecules diffuse?

• from right to left
• from left to right
• they will not move at all
• they will move in both directions equally

The cell membrane is selectively permeable, which means...

• All materials can enter and leave the cell
• Certain things can enter while others cannot
• The cell manually sorts through all materials
• Only certain cells can interact with the cell.
