So today in class we got a stamp for the diffusion lab and went over it. We went over what Osmosis is. Osmosis is when the water in a cell moves from higher concentration to lower concentration out of the cell. Then we went on to our normal and plasmolyzed cells lab. In the lab we put 2 to 3 drops of regular water on an Elodea leaf and on a seperate slide we put 2 to 3 drops of salt water on the Elodea leaf. What happened to the salt water leaf was that the water in it diffused out of the cell to get to the lower concentration of water on the outside. When this happened the chloroplasts collapsed in on each other to form a big blob of them. The structure of the cell didn't chang because plants have a strong cell wall that nothing could change its shape. Look at page 211 in your biology book.
The homework is to finish the lab on UP pages 36-39
Also begin the pre-lab
