LOCOMOTION AND MOVEMENT
Locomotion is one of the important characteristics of all living beings as plants and animals. Mostly plants are fixed but some plants move. Plants are fixed but even then they show movements as leaves of plants, touch-me-not show remarkable movements, when touched by hand. The sunflower bends towards the sunlight.

There are so many types of animals such as unicellular, small, medium size and very large size animals all show movements either they are aquatic, arboreal or terrestrial. MICROSCROPIC ORGANISMS
Microscopic animals such as Amoeba, Paramecium and euglena show following types of movements. (A) Amoeba: Amoeba is found in water. It shows creeping movements. Locomotory movements of amoeba are brought by the formation of finger like projections called pseudopodia (false feet). Several pseudopodia may project...
