Q. Assertion : If red blood cells were removed from the body and placed in pure water, pressure inside the cells increases.
Reason : The concentration of salt content in the cells increases.

Solution:

When a solution is separated from the pure solvent by means of a semipermeable membrane, the pure solvent passes through the membrane and goes to solution and a hydrostatic pressure is set up which is called as the osmotic pressure of the solution. So when red blood cells were placed in pure water, the concentration. of water is increase in the cell due to osmosis and the concentration of salt content would increase in the solution, or decrease in cell so the assertion is true but reason is false.
