NCERT Solutions for Class 11 Biology Chapter 20 - Locomotion and Movement

 

NCERT Solutions for Class 11 Biology Chapter 20 - Locomotion and Movement: Movement is one of the significant features of living beings. Animals and plants exhibit a wide range of movements. Streaming of protoplasm in the unicellular organisms like Amoeba is a simple form of movement. Movement of cilia, flagella, and tentacles are shown by many organisms. Human beings can move limbs, jaws, eyelids, tongue, etc. Some of the movements result in a change of place or location. Such voluntary movements are called locomotion. Walking, running, climbing, flying, swimming are all some forms of locomotory movements. Locomotory structures need not be different from those affecting other types of movements. For example, in Paramoecium, cilia help in the movement of food through cytopharynx and in locomotion as well. 

Class 11 Biology Chapter 20 - Locomotion and Movement of NCERT will tell you about methods of locomotion which are performed by animals vary with their habitats and the demand of the situation. However, locomotion is generally for the search of food, shelter, mate, suitable breeding grounds, favorable climatic conditions or to escape from enemies/predators.

Here are the important topics of Chapter 20 - Locomotion and Movement mentioned below:

20.1 Types of Movement

20.2 Muscle

20.2.1 Structure of Contractile Proteins

20.2.2 Mechanism of Muscle Contraction

20.3 Skeletal System

20.4 Joints

20.5 Disorders of Muscular and Skeletal System

NCERT solution will also tell you other things like repeated stimulation of muscles leads to fatigue. Muscles are classified as Red and White fibers based primarily on the amount of red colored myoglobin pigment in them. Bones and cartilages constitute our skeletal system. The skeletal system is divisible into axial and appendicular. Skull, vertebral column, ribs, and sternum constitute the axial skeleton.

Limb bones and girdles form the appendicular skeleton. Three types of joints are formed between bones or between bone and cartilage – fibrous, cartilaginous and synovial. Synovial joints allow considerable movements and therefore, play a significant role in locomotion. 

After going through Chapter 20 - Locomotion and Movement of NCERT, you must be able to answer the following questions:

  • Q1. What are the different types of movements exhibited by the cells of human body?
  • Q2. How do you distinguish between a skeletal muscle and a cardiac muscle?
  • Q3. Name the type of joint between the following:-
    • (a) Atlas/axis
    • (b) carpal/metacarpal of the thumb
    • (c) between phalanges
    • (d) femur/acetabulum

If you have any query in solving these questions then, don't worry NCERT Solutions for Class 11 Biology Chapter 20 - Locomotion and Movement will help you in answering these questions by understanding the concept behind it. Also, try to solve all the questions given in Chapter 20 - Locomotion and Movement, and Solutions for NCERT Class 11 Biology Chapter 20 - Locomotion and Movement, will help you to get the answers of all the questions which are mentioned in the NCERT book.
