__________ are energy-requiring devices that expel excess water from single cells exposed to hypotonic environments.

Question

Quizplus · Accepted Answer

Contractile vacuoles are organelles found in many single-celled organisms, including protists, that live in environments with low solute concentrations. These organelles collect excess water from the cytoplasm and expel it through a contractile process, requiring energy in the form of ATP. This helps prevent the cell from bursting due to osmotic pressure. The other options listed are not directly involved in expelling excess water from single cells.
