Cellular Respiration
Collect data again on your seeds. Is there a change in the Carbon dioxide concentration in the chamber?
Selective Permeability
There is a great Phet simulation for membrane channels. Click here to view and go through the simulation. Take screen shots and explain what is happening in terms of selective permeability. Does it matter how many channels are in the membrane? Does the severity of the concentration gradient effect the rate of diffusion? Use your data from this simulation in your selective permeability lab write-up.
Click here for the tutorial that we will go through together as a class at the end of the period :)
