hey, im a Highschool student, and i am looking for some help on my curren t experiment - diffusion accross cell membranes. We have already covered passive transport, and now i am looking for an experiment (simple, due to our limited facilities) to do.

 

Any ideas???

I have an old lab that I did with diffusion across a membrane. I could get the paper from school tomorrow and paste it onto here. It essentially involved a plastic bag that had iodine and some other things and you could show diffusion across the membrane because the liquids would change when they reacted with one another.

hi, thank for the feedback. this was my first post so i wasn't sure how it would go.

 

I think that may be similar to the passive osmosis experiment we did - involving a cellulose membrane, starch and potassium iodine. but thank you anyway, i appreciate any help i can get
