FAQs on Locomotion & Movement PPT Biology Class 11

1. What is locomotion?
Ans. Locomotion refers to the ability of an organism to move from one place to another. It involves the coordination of various body parts and systems to facilitate movement.
2. How do muscles contribute to movement?
Ans. Muscles play a crucial role in locomotion and movement. They contract and relax, causing movement by pulling on the bones of the skeleton. This contraction and relaxation of muscles allow for the flexibility and control needed for various types of movements.
3. What are the different types of locomotion in animals?
Ans. Animals exhibit various forms of locomotion depending on their characteristics and environments. Some common types of locomotion include walking, running, crawling, swimming, flying, and hopping. Each type of locomotion is adapted to suit the specific needs and abilities of the animal.
4. How do joints contribute to movement?
Ans. Joints are the points where two or more bones meet. They provide the necessary flexibility and range of motion for movement. Different types of joints, such as pivot joints, hinge joints, and ball-and-socket joints, allow for different types of movements like rotation, bending, and extension.
5. What is the role of the nervous system in coordinating movement?
Ans. The nervous system plays a vital role in coordinating movement. It receives sensory information from the environment and sends signals to the muscles, enabling them to contract and relax in a coordinated manner. The brain and spinal cord are particularly involved in the control and coordination of complex movements.
