Download Elodea Osmosis PowerPoint

Elodea Lab Terms
Cyclosis: Cyclical streaming of
cytoplasm of plant cells
Plasmolysis: Process in plant cells in
which the cytoplasm pulls away from
the cell wall due to the loss of water
through osmosis.
Turgor:Pushes plasma membrane
against cell wall – caused by the flow
of water from outside cell into the
vacuole.

• 1. Draw the elodea cell before and after salt
water was added. Label cell membrane, cell wall,
cytoplasm, chloroplast.
• 2. What did you notice about the cytoplasm and
chloroplasts in the Elodea cell before salt water
was added?
• 3. What were the differences in the Elodea cell
after salt water was added to the cell? Why did
this happen?
