Not all the times osmosis will occur if its not isotonic.
Tranportation of any material into or out of the cell by passive diffusion or facilitated diffusion require a concentration gradient.
Osmosis may result in shrinking of a cell when extracellular fluid is hypotonic and result in cell death( necrosis).
It may result in blowing up of a cell when extracellular fluid is hypertonic and result in cell explosion and lead to cell death.

No! not at all. Our body works off of the differences in the extra and intracellular fluids. Different solvents flow in and out of our cells due to this difference. If we were all iosotonic, nothing would travel in and out of the cell without help (active transport). There are many things that travel in and out of your cells by passive transport constantly because of our cells NOT being isotonic in and out.

They are not isotonic for any of the known elements. Concentration gradients exist across the cell membrane for just about everything.

Goodness no, it is helpful in most cases, but diffusion would not occur if this was the case, except randomly. If you are really interersted in this subject look at fish, they are extremely interesting in this reguard, esp. comparing fresh to salt water fish.
Hope this helps.
