Thursday 9/22

No vocabulary quiz today, changed to Friday!!!

Today we'll finish how substances and fluids cross through cell membrane notes focusing on the sodium-potassium pump.  We will then do a lab with Elodea to see how environmental conditions influence how substances pass through the membrane.

Homework- Finish membrane illustration and questions, stamped at start of class.

C.O.  Know that energy is required for movement against the concentration gradient of a cell membrane.
