What type of locomotion does amoeba have

The organ of locomotion in Amoeba is pseudopodia an the type of movement is termed as amoeboid movement. Fins and wings are the locomotory organs in fish and birds respectively.

Fins and wings are anatomical structures sometimes they are called locomotory structures or locomotory organs. These are used for their body movement. Fins are used to help the fishes to push them through the water. Answer: Cilia are the primary locomotary organs of paramecium which are covered throughout their body. Sharks swim by moving their caudal fin from side to side in a sweeping motion, which propels them forward through the water.

The large upper lobe of the caudal fin of most sharks provides most of the forward thrust. First, sharks store large quantities of oil in their liver. Fish swim by flexing their bodies and tail back and forth. Fish stretch or expand their muscles on one side of their body, while relaxing the muscles on the other side. This motion moves them forward through the water. Fish use their back fin, called the caudal fin, to help push them through the water.

Rectilinear locomotion or rectilinear progression is a mode of locomotion most often associated with snakes. It is one of at least five forms of locomotion used by snakes, the others being lateral undulation, sidewinding, concertina movement, and slide-pushing.

For several decades workers have identified four major modes of snake locomotion: rectilinear, lateral undulation, sidewinding, and concertina locomotion Mosauer ; Gray ; Lissmann ; Gans ; Jayne What is the snake trying to escape from? Answer: The snake is trying to escape from the pursuing stick. Human beings try their level best to kill the snake. Snakes have four ways of moving around.

That is why amoeboid movement has been the object of intensive investigation. Probably the amoeboid movement is the basic characteristic of unspecialized protoplasm and like most fundamental processed is difficult to explain.

Speculation about amoeboid movement goes back a hundred and thirty years to Ehrenberg, who first suggested that pseudopodia where hernia-like protrusions forced out by muscular contractions of hind part of the animal. Within a year, the alternative view was put forward that the pseudopodia were themselves inherently extensible, and pulled the rest of the animal after them, and ever since biologists have held essentially oen or the other of these views.

The elements of amoeboid movement are not difficult to grasp. At the tip of the advancing pseudopodium the plasmagel seems to spread out, while in the body of the pseudopodium the plasmasol flows forward. When the plasmasol reaches the very tip it fans out to form fresh pseudopodial wall.

At the hind end of the animal, the plasmagel seems to draw itself together and get thicker while its surface becomes wrinkled. Many theories have been put forward to explain amoeboid movements. Of these explanations only two are worth mentioning:. Surface tension theory: It was put forward by Butschli and was widely accepted for long.

According to this vies locomotion in amoeba is essentially klike the movement of a globule of mercury or other liquid produced by local reduction of surface of the fluid protoplasm that makes the mass spherical. From such a sphere an outflow will occur whereever the surface tension is locally lowered, either by internal or external changes. In such a projection the fluid will flow forward and the centre and backward along the sides.

Such streaming movement can be seen in active pseudopods of some amoeboid forms. Further, drops of certain chemical mixtures have been shown to move in amoeboid fashion because of local cecrease in surface tension. It is very simple and attractive theory which has been extended in its application to various types of activity in amoeba by Rhumbler. There are, however, a number of fully established facts which show conclusively that surface tension as applied in this theory plays but a very insignificant role in the process of movement and locomotion in amoeba.

The objections to this theory are as follows: 1. The upper surface in may species moves forward in places of backward. That is, it moves in a direction opposite to that produced in a globule of liquid by local reduction in surface tension. Many amoebae are so rigid that local reduction in surface tension can not produce movement. Amoebae sometimes cut specimens of paramecia in two pieces. This requires many times as much energy as can be developed by local reduction in surface tension.

According to this view the surface is assumed to be liquid whereas in most amoeboid forms it is gelatinized. This theory is consequently untenable.
