Question

What intracellular structure do unicellular organisms such as amoeba and

paramecia have that allow them to survive in a hypotonic soln?

( i need help asap please)

Answer 1

The structure that helps these organisms in hypotonic environments is the contractile vacuole.

As water enters the cell from the less-solute environment, the cell would normally burst; however, the contractile vacuole takes up this water and pumps it back out of the cell.
