Locomotion and Movement NEET Questions
All living organisms including plants and animals show one kind of movement or the other. The multicellular animals show two kinds of movements
(i) Locomotion
(ii) Movement of body parts.
Locomotion is the process of change of position of an organism from one place to another. It includes the acts of walking, running, crawling, swimming, hopping, gliding or flying in the air. It enables animals to move away from enemy or away from undesirable places. It enables the animal to find its mate or partner for Sexual reproduction. It helps in searching and procuring food and water It enables them to migrate to more favourable locations of food, shelter and suitable places of egg laying.
Movement of body parts in relation to body axis is the other form of movement in animals. Such movements serve functions such as visceral organs show different kinds of movement. Due to the movement of visceral organs, propel food in the animals are able to respire, alimentary canal, pass urine and pump and circulate blood in the body. Food capture and its ingestion involve the movements of toung, jaws, limbs, etc
