✯A prokaryotic cell is the type that has no membrane-bound nucleus. Prokaryotic cells are simple and primitive, lacking true organelles.

✯When RBCs are kept in concentrated saline solution then such solution is said to be hypertonic. Hence, exosmosis i.e., water will move from inside to outside of RBC through its cell membrane due to this, RBCs will shrink.
