Osmosis
QuickTime™ and a
TIFF (Uncompressed) decompressor
are needed to see this picture.
• Hypotonic Solutions
• Example:
• Less dissolved solutes in
solution than in cell.
(more water in solution!)
• Net movement of water
into cell.
• Plant cell• Animal cell-
Osmosis
• Hypertonic Solutions
• Example:
• More dissolved solutes
in solution than in cell
(less water in solution)
• Net movement of
water out of cell

What happens to cells?
• Watch videos to see what happens to plant
and animal cells in various solutions!

Think about it?

• If you were getting an
IV to rehydrate your
cells, what type of
solution should it be?
• What if you just want
medicine to travel
around with your
blood but not enter
into your cells?
Think about it?
• If you want flowers to
stand up nice and
straight, what type of
solution should you
put them in?
• Why are plants on the
side of the highway
often wilted after
snowmelt?
