FAQs on Locomotion & Movement in One Shot (NCERT) Video Lecture - Biology Class 11 - NEET

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 muscles to produce movement.
2. What are the different types of locomotion?
Ans. There are different types of locomotion observed in organisms, including walking, running, crawling, swimming, flying, and hopping. Each type of locomotion is adapted to the specific needs and environment of the organism.
3. How does movement occur in organisms?
Ans. Movement in organisms is facilitated by the contraction and relaxation of muscles. Muscles work in pairs, with one muscle contracting while the other relaxes, allowing for movement. Nerves send signals to the muscles, initiating the contraction and relaxation process.
4. How do organisms maintain balance during movement?
Ans. Organisms maintain balance during movement through various mechanisms. The inner ear plays a crucial role in detecting changes in position and movement, sending signals to the brain to maintain balance. Additionally, visual cues and proprioception (awareness of body position) help in maintaining balance while in motion.
5. How does locomotion differ in different organisms?
Ans. Locomotion differs in different organisms based on their anatomical features, body structure, and environmental adaptations. For example, humans use bipedal locomotion, walking on two legs, while snakes use lateral undulation to move. Aquatic organisms have adaptations like fins or flippers for swimming, while birds have wings for flying. Each organism has evolved unique locomotory mechanisms suited to their specific needs.
