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.

What is the name of the process in which molecules move from an area of high concentration to an area of low concentration across a selectively permeable membrane?

• Diffusion

• Osmosis

• Active Transport

Where is there a low concentration of dye?

• at the bottom of cup
• in the color
• at the top of cup 
• no concenteraion gradient

Permeable means

• things can pass through
• the concentration levels are different
• it is permanent
• things are stuck

Against the concentration gradient

low to high

uses energy/ATP

• diffusion

• osmosis

• active transport

What does “high concentration area” mean?

• Spread out
• Tightly packed together
• Uncrowded
• Spacious
