What is required for locomotion in human beings and the majority of multicellular organisms?

Step-by-step solution

Movement is one of the significant features of living beings.Streaming of protoplasm in the unicellular organisms like Amoeba is a simple form of movement.Movement of cilia, flagella and tentacles are shown by many organisms. Animals perform locomotion for the search of food, shelter, mate, suitable breeding grounds, favourable climatic conditions or to escape from enemies/predators. Some specialised cells in our body like macrophages and leucocytes in blood exhibit amoeboid movement. Locomotion requires a perfect
