WebNov 29, 2024 · Exosmosis occurs if the cells are in hypertonic solutions due to which the cells shrink. What happens if RBC is kept in water? Water transitions from a high concentration to a lower concentration. This happens when the concentration of the solution is greater than the concentration of the inside of the cell, which allows RBC to shrink.
