The prokaryotic cell is typically described as a primitive cell because it lacks nucleus and do not possess most of the remaining cell organelles. The organisms that possess prokaryotic cells are called prokaryotes. Examples of such organisms are bacteria and archaea.

Answer:
Distilled water is hypotonic with respect to the blood plasma of our body.
Explanation:
If distilled water is used in place of saline and injected intravenously then red blood cells of that patient"s body will start to swell as the osmotic pressure of the blood is very much greater than that of distilled water.
That"s why, to maintain homeostasis 0.9% NaCl is used as saline solution because RBC is isotonic with 0.9% NaCl solution.
