Locomotion In Paramecium

Locomotion in Paramecium: 

    The body of a paramecium is covered all over by a large number of short thread like extensions, of plasma membrane, called cilia. The locomotion in paramecium takes place by the beating of these cilia and hence is called ciliary movement. Locomotion is brought about by alternate power strokes and backward power stroke of hundreds of these cilia push body forward.

Locomotion in Cockroach: Locomotion in arthropods is brought about by the interaction of the muscular and exoskeletal system of its jointed legs. The legs act as efficient levers and make the movement much more fast and swift. In cockroach muscles are attached to the inside of exoskeleton of legs. These anatagonistic muscles work in opposition to one another. Contraction of these flexor and extensor muscles move the appendages and the animal. The swift and fast movement of an arthropoda makes it better adapted to catch a prey and escape a prdator, a key to their success which resulted in their wide spread distribution. Cockroach like many other insects is blessed with wings for flight adding a lot of their mobility. Locomotion-in-cockroach(learn-4-future.blogspot.com)

Locomotion In Protozoa: 

          Locomotion in Protozoa, a group of protoctists is usually carried out by appendages like outgrowths of the cell body. These are of three types i.e. Pseudopodia in Amoeba, Cilia in paramecium and flagella in Euglena.

Locomotion In Amoeba

Locomotion In Amoeba: 

     Locomotion in Amoeba is called amoeboid movement and takes place by the help of pesudopodia which are temporarily formed finger like projections of cytoplasm. A pseudopodium, formed in the direction of movement, attaches to the substratum and by a contractile process whole cytoplasm flows into it. A fresh pseudopodium is formed father off in the same direction and cytoplasm is now pulled into it. The Amoeba thus moves in that direction by continuously repeating this process. Amoeboid movement depends upon alternate change of cytoplasm into fluid like Sol and a jelly like gel form.

Locomotion In Earthworm

Locomotion in Earthworm: 

     Earthworms, being terrestrial, are adapted to locomotion in soil. Their movement is brought about by the contraction of two sets of muscles and their body fluid, serving as a hydrostatic skeleton. Contraction of longitudinal muscles shortens the body and contraction of circular muscles lengthens (elongation) the body. As a result of interaction of muscles contractions and compressed body fluid an earthworms crawls.   

          In addition bristles called setae extending from the body wall in each segment grasp the soil functioning as hold fast to take the grip of the soil.

Locomotion In Star fish

 Locomotion In Star fish: 

    In Star fish locomotion in controlled by a special water vascular system. Water is drawn into the body through a small opening in the central disc and is passed through a ring canal to five radial canals one running along each arm. Along each of these cannals a large number of hollow, muscular tube feet are present. The upper part of a tube foot, connected with the canal, is a bulb shaped ampulla whereas its bottom part is a sucker. When ampullae contract water forces the tube feet to lengthen and suckers become attached to on object. When sucker muscles contract the water is pushed back into the ampullae, making the tube feet flaccid, losing the grip and the star fish is pulled forward. Using its hundreds of feet a star fish creeps along the rock and other solid objects in the sea. Using its arms, it can also swim in water.

Locomotion In Snail

Locomotion in Snail: 

      Locomotion is snail, like other molluscs, takes place by a specialized organ, the foot. Snail moves by the contractions of muscles underside the foot. These contractions are brought about under the influence of hydrostatic pressure of the body fluid. The waves of contraction from front to rear push the animal forward. This movement is made easy by a slimy secretion of the mucuous gland poured in front of the foot and animal virtually slips forward. This gives rise to the familiar shinning tract left by a moving snail.

Locomotion In Animalia

Locomotion in Animalia: 

     Locomotory organs of animals are built on a quite different plan than those of the protoctists. Instead of being appendages of a single cell, the locomotory organs of animals are far more developed and work by the co-ordinated action of muscles and skeleton.

Locomotion In Jelly Fish

Locomotion in Jelly fish: 

      A jelly fish has an umbrella shaped body which floats freely on water or swims by contracting its muscle cells forcing the water powerfully out of its mouth and umbrella to create a jet propulsion effect. The jelly fish moves in jerks in the direction opposite to the expelled water.

Locomotion In Euglena

Locomotion in Euglena: 

      The locomotory organelles in Euglena are flagella and the movement brought about by flagella is called flagellary movement. The flagella are structurally similar to the cilia with the difference that the flagella are very few, if not single, relatively larger in size and beat in a whip like fashion. Locomotion in brought about by the alternate right and left power strokes and recovery strokes.
