Sailors cannot drink salt water because...

• it is poisonous to humans
• it is hypertonic to human tissue
• it is hypotonic to human tissue
• it is isotonic to human tissue.

A cell in a hypotonic solution will

• swell
• shrink 
• stay the same size
• impossible to tell

The picture is an example of _________________.

• osmosis
• isotonic
• diffusion
• active transport

Which plant cells are bathed in a hypotonic solution?

• the ones in the picture on the left
• the ones in the picture on the right
• Both groups of cells pictured
• Neither group of cells pictured

Which group of cells appear to have been treated with a salt water solution?

• The cells in the picture on the left
• The cells in the picture on the right
• Both groups of cells
• Neither group of cells
