Everyone in my biology class got assigned organelles, and we need to make models of each one out of a material. I need a material to make a cell wall out of, but I can't think of one. Ideas? Thanks!

Cardboard.  You need a cardboard box.  Make some holes in it with pins.  Tell the class that some of those represent where the plasmodesmata are.  Now go look up "plasmodesmata."

dialysis tubing.....it can simulate diffusion which happens in a real cell wall.
