Question

a cell is placed in a solution A and it swells up what kind of solution is it ? why does it happen ?

Answer 1

hypertonic solution.

This is because the cell is containing less water than its surroundings

Answer 2

Hey there

This happens if the solution is a hypotonic solution. In this solution, there's only a small amount of the solute when compared to the amount of water.

As there's more concentration of the molecules of water around it, it may get into the cell.

That's why it swells!

Thanks
