Question

What is hypertonic and isotonic solution?

Answer 1

An isotonic solution refers to two solutions having the same osmotic pressure across a semipermeable membrane. This state allows for the free movement of water across the membrane without changing the concentration of solutes on either side.
A hypotonic solution is one in which the concentration of solutes is greater inside the cell than outside of it, and a hypertoni solution is one where the concentration of solutes is greater outside the cell than inside it.
