A red blood cell has been placed into three different solutions. One solution is isotonic to the cell, one solution is hypotonic
Dmitry [639]

The type of solution in each beaker based on cell's reaction are :

  • Isotonic solution : Normal reaction
  • Hypotonic solution : The cell becomes turgid
  • Hypertonic solution : The cell becomes deformed

<h3>Matching each solution to the cell reaction </h3>

When the red blood cell is placed in an isotonic solution the solvent flows in and out of the blood cell at the same rate, when the cell is placed in a hypotonic solution the solvent flows into the cell at a faster rate causing the cell to swell ( becomes turgid ) also when the cell is placed in a hypertonic reaction the cell becomes deformed becomes it loses more water than it absorbs.

Hence we can conclude that The type of solution in each beaker based on cell's reaction are : Isotonic solution : Normal reaction, Hypotonic solution : The cell becomes turgid, Hypertonic solution : The cell becomes deformed
