Overview

Locomotion and movement are basic characteristics of living organisms. Movement may occur at the cellular level, as in amoeboid, ciliary, and flagellar movement, or at the level of the whole body, as in locomotion. In higher vertebrates, locomotion depends on the coordinated action of the skeletal,

Key Concepts

Movement of the whole organism from

Movement of the whole organism from place to place is known as locomotion. It helps in obtaining food, escaping predators, finding mates, and locating

The main types are amoeboid

The main types are amoeboid, flagellar, ciliary, and muscular movement. Amoeboid movement uses pseudopodia, flagellar movement uses flagella, ciliary

Amoeba changes its shape by forming

Amoeba changes its shape by forming temporary cytoplasmic projections called pseudopodia. These projections help in locomotion and feeding.

Flagella are thread

Flagella are thread-like locomotory organelles of flagellated protists. This movement is best seen in Euglena.

Cilia are small vibratile ectoplasmic processes

Cilia are small vibratile ectoplasmic processes. Their movement is synchronous and coordinated. It helps in the movement of substances inside the body
