You are watching: Do you think osmosis occurs when a cell is in an isotonic solution
Fish cells, choose all cells, have actually semipermeable membranes. Eventually, the concentration the "stuff" ~ above either side of lock will even out. A fish that stays in salt water will have somewhat salty water inside itself. Placed it in freshwater, and also the freshwater will, v osmosis, get in the fish, resulting in its cell to swell, and also the fish will die. What will happen to a freshwater fish in the ocean?
Imagine you have a cup that has actually (100 : extmL) water, and also you add (15 : extg) of table street to the water. The street dissolves and the mixture the is now in the cup is comprised of a solute (the sugar) that is dissolved in the solvent (the water). The mixture of a solute in a solvent is dubbed a solution.
Imagine currently that you have a second cup through (100 : extmL) of water, and also you include (45 : extg) that table sugar to the water. Just like the first cup, the street is the solute, and the water is the solvent. But now you have two mixture of different solute concentrations. In compare two options of unequal solute concentration, the equipment with the higher solute concentration is hypertonic, and the equipment with the lower solute concentration is hypotonic. Solutions of equal solute concentration are isotonic. The very first sugar equipment is hypotonic come the second solution. The 2nd sugar systems is hypertonic come the first.
You now add the two remedies to a maker that has been split by a semipermeable membrane, v pores that room too tiny for the sugar molecules to pass through, however are huge enough for the water molecule to pass through. The hypertonic systems is one one side of the membrane and the hypotonic systems on the other. The hypertonic solution has a lower water concentration than the hypotonic solution, for this reason a concentration gradient the water currently exists throughout the membrane. Water molecule will relocate from the next of higher water concentration come the next of lower concentration until both services are isotonic. At this point, equilibrium is reached.
Red blood cell behave the same method (see number below). Once red blood cells room in a hypertonic (higher concentration) solution, water flows the end of the cell quicker than it comes in. This results in crenation (shriveling) of the blood cell. On the various other extreme, a red blood cell the is hypotonic (lower concentration exterior the cell) will an outcome in an ext water flowing right into the cell 보다 out. This results in swelling of the cell and also potential hemolysis (bursting) that the cell. In one isotonic solution, the circulation of water in and out that the cell is happening in ~ the very same rate.
