Multiple Choice Questions (MCQs)


Question 1:  Which of the following parts of our body help us in movement?

  1. Bones
  2. Skin
  3. Muscles
  4. Organs

Choose the correct answer from the option below.
(a) (1) and (3)
(b) (2) and (4)
(c) (1) and (4)
(d) (2) and (3)

Solution 1:  The right thing for which selection is made is (a) (1) and (3). 

Our bones, muscles, and joints form our musculoskeletal system and enable us to do movement from one place to another.


Question 2:  Which of the following joints are immovable?

(a) Shoulder and arm     

(b) Knee and joint

(c) Upper jaw and skull 

(d) Lower jaw and upper jaw

Solution 2:  The right thing for which selection is made is (c) Upper jaw and skull. 

Immovable joints are those that do not allow movement at joint locations.
Upper jaw and skull are immovable or fixed joints. Shoulder and arm Ball are socket joints. Knee and joint are Hinge joint. Lower jaw and upper jaw are also Hinge joint.


Question 3:  Which of the following organisms does not have both muscles and skeleton for movement?

(a) Dog     

(b) Snail

(c) Earthworm   

(d) Human being

Solution 3:  The right thing for which selection is made is (b) Snail. 

Snail does not have both muscles and skeleton for movement. They have an exoskeleton that is the external skeleton that supports and protects an animal's body. Exoskeletons are known as "shells". Snails move with the help of muscular foot that has two sets of muscles.

Dog and human beings have musculoskeletal system for movement.
Earthworms have a segmented hydrostatic skeleton. A hydrostatic skeleton, or hydro skeleton, is a flexible skeleton formed by a fluid-filled compartment within the body. The alternate contraction and relaxation of muscles and pressure of the fluid helps in burrowing.

Question 4: Underwater divers wear fin-like flippers on their feet to
(a) swim easily in water
(b) look like a fish
(c) walk on water surface
(d) walk over the bottom of the sea (sea bed)

Solution 4:  The right thing for which selection is made is (a) swim easily in water. 

Underwater divers wear fin-like flippers on their feet to swim easily in water.
Fin-like flippers (swim fins) help divers in swimming efficiently under the sea without using much force.


Question 5:  Snail moves with the help of its

a)      shell                    

b)      bone

c)       muscular foot  

d)      whole body

Solution 5:  The right thing for which selection is made is (c) muscular foot. 

Snails moves with the help of its strong muscular foot. Snail is a small animal with a long, soft body, no legs, and a spiral-shaped shell. Snails move very slowly. Shell is the external skeleton that supports and protects an animal's body.

Question 6:  How many muscles work together to move a bone?

a)      One

b)      Two

c)       Three

d)      Four

Solution 6:  The right thing for which selection is made is (b) Two. 

Two muscles i.e. a pair of muscle work together to move a bone. Muscles move body parts by contracting and then relaxing. Muscles can pull bones, but they can't push them back to the original position. So, they work in pairs and when one muscle of the pair contracts, then the other muscle of the pair is relaxed.


Very Short Answer Type Questions


Question 7: Name the type of joints of your hand which helps you to grasp a badminton racquet.

Solution 7:  The joint of hand which helps us to grasp a badminton racquet is hinge joint . Hinge joints are those that allowing bones to move in one direction back and forth with limited motion along other planes. They facilitate bending and straightening actions. The fingers, toes, elbows, knees, and ankles contain hinge joints. 


Question 8: What would have happened, if our backbone was made up of one single bone?

Solution 8:  Our backbone is made up of 33 small bones called vertebrae. If our backbone was made up of one single bone, then we would not have been able to twist our waist.


Question 9: Provide one word answer to the statements given below.

  1. Joint which allows movement in all directions.
  2. Hard structure that forms the skeleton.
  3. Part of the body with a fixed joint. .
  4.  Help in the movement of body by contraction and relaxation.
  5. Bones that join with chest bone at one end and to the backbone at the other end.
  6. Framework of bones which gives shape to our body.
  7. Bones which enclose the organs of our body that lie below the abdomen.
  8. Joint where our neck joins the head.
  9. Part of the skeleton that forms the earlobe. 

Solution 9:

  1. Ball and socket joint
  2. Bones
  3. Upper jaw with skull
  4. Muscles
  5. Rib
  6. Skeleton
  7. Pelvic bones
  8. Pivotal
  9. Cartilage


Question 10: Write the type of joint which is used for each of the following movements:

  1. A cricket bowler bowls the ball.
  2. A girls move her head in right and left direction.
  3. A person lifts weights to build up his biceps. 

Solution 10:

  1. It is a Ball and socket joint that helps in movement of shoulder.
  2. It is a pivot joint that connects our head to the neck.
  3. It is a hinge joint that helps in movement of the elbow.

Write the types of movements seen in each animal.

  1. Duck
  2. Horse
  3. Kangaroo
  4. Snail
  5. Snake
  6. Fish
  7. Human being

Solution 12: The types of movements seen in each animal are as follows:

NCERT Exemplar Solutions Class 6 Science Body Movement-1


Question 13: Boojho fell off a tree and hurt his ankle. On examination, the doctor confirmed that the ankle was fractured. How was it detected?

Solution 13:  The doctor firstly, examines his ankle and must have observed that a swelling around his ankle. To sure that the ankle fractured, the doctor taken an X-ray of his ankle and X-ray images confirm injury/fracture in his ankle.


Question 14: Bones are hard structures and cannot be bent. But, we can still bend our elbow, knee, etc. How is this possible?

Solution 14:  We can bend elbow and knee because of hinge joint. Our elbow and knee are made up of two or more bones which are joined to each other by a joint called hinge joint. Hinge joints are those joints that allow movement along one plane/direction. They facilitate bending and straightening actions. That’s why we can bend our knee and elbow easily.


Question 15: Which type of movement would have been possible if

  1. Our elbow had a fixed joint.
  2. We were to have a ball and socket joint between our neck and head. 

Solution 15:  

  1. Fixed or Immovable joints are those that do not allow movement at joint locations. If our elbow had a fixed joint, we would not be able to bend/fold our elbow.
  2. A ball and socket joints are those that allow movement in all directions. So, If we were to have a ball and socket joint between our neck and head, we would be able to rotate our head in all direction (360°).


Question 16: Earthworms are known as farmer’s friends. Why?

Solution 16:   Earthworms are known as farmer’s friends because of their activity in soil. Their body excretes undigested materials that also increase the fertility of soil. Earthworms feed on plant debris (dead roots, leaves, grasses, manure) and soil.  They also increase decomposition of organic wastes, improve nutrient availability, promote plant growth, all of which help improve farm productivity and helps the crops to grow, that is why earthworms are known as farmer’s friends.

Question 18: How is the skeleton of a bird well-suited for flying?

Solution 18:  The skeleton of a bird is well-suited for flying because:

1. The bones of birds are thin, hollow and light in weight.

2. The strong shoulder bones, which help them to fly easily.

3. The forelimbs of birds are modified as wings for fly in air.

4. They have a streamlined body, which reduces the air resistance.

5. The breast bones are modified to hold flight muscles which are help the birds to move the wings up and down for flying.


Question 19: In the figure given below, there are two snakes of the same size slithering on sand. Can you identify which of them would move faster and why?

NCERT Exemplar Solutions Class 6 Science Body Movement-2

Solution 19:  Snakes do not have legs; they have muscles and rough scales that help them in their locomotion. Snake move in a wavy motion and they form loops in its body while slithering. Each loop of the snake helps it to a forward push by pressing against the ground. The conclusion is that the snake with a larger number of loops will move much faster than the snake with lesser number of loops.

As we can see in figure that snake A formed more loops while slithering. So, snake A will move faster than snake B.
