Locomotion is known as the movement of an individual from one place to another. Both the unicellular and the multicellular organisms show locomotion. It is possible with the help of different structures. These structures are essential for both the movement and locomotion of the internal and external body parts. The tentacles of the hydra help it to capture the prey and serve as organs as means of locomotion. Similarly, the paramoecium uses cilia for locomotion and for capturing food. Movement and locomotion are not different entities. It can be said that all locomotions are movement but all movements are not locomotion. As movement can be done at a place only but for locomotion, we need to move from one place to another.
