In an experiment, using the elodea stalk, you are able to expose more underlying tissue and the process can be executed more quickly and it's easy to replicate the natural position for a more realistic result.
hope this helps
A cell membrane does not actually maintain homeostasis by itself. The term homeostasis refers to maintaining a relatively stable internal environment inside of a multi-cell organism. Since the internal environment is the interstitial fluid that is around each and every cell, then homeostasis has more to do with what is outside of a cell than what is inside of it. :)
