The diffusion of WATER across a semi-permeable membrane is

• osmosis
• diffusion
• endocytosis
• exocytosis

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.

A cell will _____________________ in a hypertonic solution.

• swell
• shrink
• will not change
• will explode

A cell will __________________ in a hypotonic solution.

• swell and perhaps burst (lyse)
• shrink
• the size of the cell will not change
• the size of the cell will change from large to small and from small to large

After examining this diagram showing the concentration of water inside and outside of the cell, identify the tonicity of the solution.

• hypertonic

• hypotonic

• isotonic

The solution surrounding the cell in Diagram B, would be defined as:

• hypertonic

• hypotonic

• isotonic

After examining this diagram showing the concentration of water inside and outside of the cell, identify the tonicity of the solution.

• isotonic

• hypotonic

• hypertonic

The cell below is in a _________ solution.

• Hypotonic
• Hypertonic
• Isotonic

The cell below is in a _____________ solution.

• Hypertonic
• Hypotonic
• Isotonic

This egg has shrunk, what type of solution was it placed in?

• hypotonic solution

• hypertonic solution

• isotonic solution
