Explanation / Answer

Uses its contractile vacuole to remove excess water

A. Paramecium have a particular organelle called a Contractile (or Expulsion) Vacuole.

As water diffuses into the paramecium over its film, the contractile vacuole ingests the pointless water, and through withdrawal, expulses the water out of the cell.

This vacuole is a kind of administrative component. Without it, the paramecium would swell and lyse from an excessive amount of water admission.
