8.2 Cell Transport

 Turn in VIRTUAL Inquiry Lab: Salty Cells & review

Revisit the live video of red onion cells in different solutions. 
(Here is another video that may be helpful for viewing cells.)

What you observed happening when salt water was added was called plasmolysis - shrinking of the cytoplasm away from the wall of a living cell due to outward osmotic flow of water (write definition on page with Salty Cells lab)

Announcements:
Spring Break: 3  weeks away!
Tutorial Thursday, assembly Friday
Midterm Progress Reports go out tomorrow
End Q3 is Thurs 4/7; Bio Honors due week of 3/28-4/1
