Osmosis

Try it your self-- click here and look and see what a RedBloodCell does in each type of solution!!!

The picture above shows what happens to a red blood cell in three different types of solutions. Hypertonic (cell will shrink), hypotonic (cell will swell or burst), or isotonic (the cell stays the same). Click on the link below to read about these types of solutions!!

OSMOSIS

The picture above is how a plant cell will look in three different types of solutions (hypertonic, hypotonic, and isotonic). In a hypertonic solution, notice how the cell is pulled away from the cell wall. In a hypotonic solution, the plant cell looks really full but usually will not burst because of the rigid cell wall. The plant cell in an isotonic solution does not show any stress and appears to be "normal".

Just another info page on osmosis

The link above explains osmosis. Please use this interactive site to help you understand how water flows in and out of a cell.
