MOVEMENT  

All living organisms show some type of movement Animals however move more freely It is obvious when you call your pet dog it comes running  The same is not true of a tree  This ability to move has been used as a criterion to differentiate plants and animals Though movement is quite common in plants  it is not always apparent Animals possess definite organs of locomotion The act of moving from place to place is known as locomotion  It involves the movement of the whole body as in walking  running swimming or flying  Movement is the change in position of only a part of the body as movement of stem towards light in plants 

Why animals need locomotion ?

Locomotion helps the animals in many ways 

 Look at the mode of nutrition in plants and animals  Plants are autotrophic while animals are heterotrophic What it means is that plants can prepare their own food even while being fixed at a particular place Animals have to move from place to place in search of food since they are heterotrophic Locomotion helps the animals to move in search of food Locomotion enables animals to move from place or environment to a place or environment  It helps them to escape from their enemies and predators  It helps animals to find their partners for reproduction and to move to areas for egg laying or rearing of the young ones 

HUMAN BODY AND ITS MOVEMENTS

Let us start by finding out the movements which we make daily and then try to move the various parts of the body Through this activity we can find out

which body parts cannot move at all 

which body parts move in one direction only 

which body parts move in various directions  Note down your observations living organisms show some type of movement Animals however move more freely It is obvious when you call your pet dog it comes running The same is not true of a tree This ability to move has been used as a criterion to differentiate plants and animals Though movement is quite common in plants it is not always apparent Animals possess definite organs of locomotion The act of moving from place to place is known as locomotion It involves the movement of the whole body as in walking running swimming or flying Movement is the change in position of only a part of the body as movement of stem towards light in plants Look at the mode of nutrition in plants and animals Plants are autotrophic while animals are heterotrophic What it means is that plants can prepare their own food even while being fixed at a particular place Animals have to move from place to place in search of food since they are heterotrophic Locomotion helps the animals to move in search of food Locomotion enables animals to move from place or environment to a place or environment It helps them to escape from their enemies and predators It helps animals to find their partners for reproduction and to move to areas for egg laying or rearing of the young ones
