Answer:
It would swell and then burst
Explanation:
If a unicellular organism is surrounded by a hypotonic solution it would swell and burst. This is caused by the fact that hypotonic substances prefer to go into substances with a higher solute (The unicellular organism). If the hypotonic solution would enter into the organism it would swell up and burst.
