Detailed explanation-1: -A Paramecium propels itself by whip-like movements of the cilia, which are arranged in tightly spaced rows around the outside of the body.

Detailed explanation-2: -The cilia help the Paramecium in moving or locomotion. It also helps the organism to move its food to the oral cavity. The cilia are arranged uniformly throughout the body in longitudinal rows.

Detailed explanation-3: -Cilia are essential for the movement of paramecia. As these structures whip back and forth in an aquatic environment, they propel the organism through its surroundings.

Detailed explanation-4: -Paramecia are covered with cilia that beat like thousands of tiny oars, propelling the creatures through the water. At the same time, cilia around the paramecium’s “oral groove” sweep nutrients inward, providing all-important nourishment.
