Glad you asked...
The best and easiest way to make a 3D cell model is use jello to represent the cell mass and body and other foods like fruit and pasta to represent the organelles. You can shape and cut the jello to give 3D presentation. Label all the cell parts and organelles with paper signs on tooth pick stakes. Cell pic: http://startswithabang.com/wp-content/up...
Then again, this answer might help you...
A 3D Plant Cell Project can be built by using jelly, plastic sandwich bags, yarn, pepper, green grapes, mandarin oranges and spaghetti (uncooked).
