Class Notes or Information

1.   Cell membrane structures




Today’s Objective 1)   Collect data for osmosis graphs of sweet potatoe in salt and sugar solutions

2)   Understanding the difference between selectively permeable and semipermeable

3)   Comparing Active to Passive transport across cell membranes



Number One

Potato lab objective.

Collect data and make graph


Reference link



Would like to recruit two lab groups to do a full day run of data collection for Friday. Contact asap.


We may want to alter both the concentration of sugar and salt and change the shape of the potato



Number Two

In preparation for dialysis lab


Semi permeable verse Selectively Permeable

Movement across membranes with proteins


Modeling membranes



Comparison Youtube



Analogy youtube





Number Three

Passive, Facilitated verses Active transport


Step one: Passive compared to Active




nice graphic analogy of kayaking as a way to compare active to passiv transport




A good English video



A..um..written powerpoint.



A..hands on verbal description
