The effect on epidermal cell of onion and red blood cell in hypotonic solution
Answers
Answer: (RBC means red blood cells)
A Hypotonic solution is a solution that contains a lesser solute concentration. If RBC is kept in a hypotonic solution, the water molecules will move from the hypotonic solution to RBC. This process is called osmosis in which the water molecules move from lower solute concentration to higher solute concentration through cell membrane RBC. Due to this, the cell membrane of RBC will not be able to tolerate the pressure and it will burst eventually.
If onion peel is kept in a hypotonic solution, the water molecules will move from the hypotonic solution to onion cells. This process is called osmosis in which the water molecules move from lower solute concentration to higher solute concentration through the cell wall of the onion. As onion cells possess a cell wall along with the cell membrane the onion cell will take a longer time to burst than RBC but it will burst eventually.
