It is because the salt in the salt water will absord the fresh water in the cell, dehydrating it and making it shrivel up. The red blood cell shrivels up because of the process of osmosis. Water flows from an area of high concentration to lower concentration. If there is a lot of solute (picture a bunch of particles in water) then the water has a low concentration and a high concentration of solute. The RBC is sitting in extra cellular fluid (ECF). Within the RBC is intracellular fluid (ICF). If there is a lot of salt in the ECF or water like your example this means the fluid has a low concentration. Therefore, water from the ICF of the red blood cell will go out into the ECF so that its osmolarity will equal the osmolarity of the ECF. When more fluid goes to the ECF it is increasing it's concentration relative to the NaCl particles. Cells do this to maintain equality and balance.
Blood has a salt concentration of 0.9%. So a 1.5% salt solution will cause fluid to flow from the area of low solute concentration (blood cells) to an area of high solute concentration (water solution).
well it does not actually dissolve... it shrinks...it tries to reduce the concentration of the salt water by giving off its own water...so it shrinks down
I believe it would crenate.
A red blood cell, when placed in 50% NaCl solution, will shrink as the water contained in it will be sucked into the surrounding solution doe to the osmotic pressure difference.
Osmosis may occur in either direction across the cell membrane.
9% NaCl is a hypertonic saline solution. Red blood cells will appear to shrink as they lose water out of the cell membrane and into the saline solution.
hypertonic solution
When red onions are placed in a solution with fifteenth percent salt and forty- five percent water, the water leaves the red onion cells through osmosis until the cell membrane will eventually collapse.
Hypotonic solution
they absorb water through the permeable membrane and on ovr absorbing...they burst up
Since a 9% saline solution is hypertonic as compared to the cell, it would crenate (crush or shrink).
Since a 9% saline solution is hypertonic as compared to the cell, it would crenate (crush or shrink).
If a red blood cell is placed in an isotonic solution then nothing should happen physically because an isotonic solution is one that has the same solute concentration as the red blood cell itself.
hypotonic solution
A red blood cell when placed in salty solution shrinks and becomes wrinkled.
