- Finish Handout 25
- Review cell parts (see handouts 22, 23, and/or practice quiz on Schoology)
Today we discussed the answers to handout 20. Compare your answers to mine and revise your answers as needed. Most students needed to update at least their definition of ecosystem. We started our investigation into elodea and osmosis by observing the elodea plant in salt water. Complete both sides of handout 25. I've included pictures below of the elodea in freshwater (left) and salt water (right). I've also included the drawing sheet (below) so you can make your sketches. The drawing box represents the cell wall. You're just drawing one cell. Label as required from the instructions on handout 25.
You received one handout today.
- Handout 25: Elodea and Osmosis
Both images below show the elodea cells in salt water. However, the image on the right shows the cells just as they were placed in. Thus, you can assume that it is the same as when the cells are placed in freshwater.
