Question

The process of plasmolysis can be reversed if the cell is placed in ? (a) Hypertonic solution (b) Isotonic solution (c) Hypotonic solution (d) Saturated solution

Answer 1

by keeping the cell in hypotonic solution

Answer 2

"(c) Hypotonic solution

""Plasmolysis"" is the ""process"" by which a ""cell loses"" water to its surroundings. This happens when it is ""placed"" in a ""hypertonic solution"", that is, when the solute concentration of the surrounding is higher than that inside the cell water moves from ""inside the cell to outside"".

However, when a ""cell is placed"" in a hypotonic solution, that is, when the solute concentration of the surrounding is lower than that inside the cell water moves from the surrounding into the cell. This is called reverse plasmolysis.

There is no movement of water when a ""cell is placed"" in an ""isotonic solution""."
