Question

what happen to animal cell when it is placed in a very dilute external medium? why?

Answer 1

the cell membrane will rupture because animal cell does not have cell wall

Answer 2

Here the animal cell is kept in dilute external medium that means hypotonic solution. Hypotonic solution: In this solution the solute concentration is lower than that of thecell fluid concentration. As a result, water moves into the cell from the surrounding medium through a cellmembrane.
