Living Environment State Diffusion Lab Review

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.

Which letter is pointing to a protein channel?

• A
• B
• C
• E

• Diagram F shows the end result of diffusion
• Diagram G shows the end result of diffusion
• Diagram H shows the end result of diffusion
• Diagram J shows the end result of diffusion

• The purple starch is too large to pass so the water will move from side B to side A
• The large purple starch will move from side B to side A

Why is diffusion and osmosis important to cells?

• It allows them to take in materials without using energy.
• It allows them to reproduce.
• It allows them to absorb sunlight.
• It allows cells to use all energy.
