Class 10 Science Chapter 6 MCQ : Control and Coordination MCQs Quiz

Chapter 6, Control and Coordination, explains how living organisms detect and respond to stimuli. It begins by exploring the nervous system in animals, detailing the structure of neurons, the mechanism of impulse transmission via synapses, and the roles of different parts of the human brain (forebrain, midbrain, and hindbrain). The chapter distinguishes between reflex actions and voluntary actions. Furthermore, it covers chemical coordination through the endocrine system, describing the functions of glands like the pituitary, thyroid, and adrenal. In plants, the concept of coordination is explained through plant hormones (auxins, gibberellins, cytokinins) and movements like tropism (phototropism, geotropism) and nastic movements.

Conclusion

Scoring well in Class 10 Science requires a clear understanding of how systems work together. By attempting this Control and Coordination Class 10 MCQs Quiz, you have tested your knowledge of the intricate network of nerves and hormones. Regular practice of these Class 10 Science Chapter 6 Quiz questions will help you remember crucial distinctions between chemical and nervous control, as well as the specific functions of plant hormones. Make sure to revisit the NCERT diagrams and explanations for any questions you missed. Keep practicing to ace your board exams!

FAQs on Class 10 Science Chapter 6 MCQ : Control and Coordination MCQs Quiz

1. What is the structural and functional unit of the nervous system?
   The neuron is the structural and functional unit of the nervous system.
2. Name the part of the brain which controls posture and balance of the body.
   The Cerebellum controls posture and balance.
3. What is a synapse?
   A synapse is the junction between two neurons where the electrical signal is converted into a chemical signal to transmit the impulse to the next neuron.
4. Which gland is known as the “Master Gland”?
   The Pituitary gland is often referred to as the “Master Gland” because it controls the functions of other endocrine glands.
5. Define geotropism.
   Geotropism is the growth movement of a plant part in response to the force of gravity; roots show positive geotropism, while stems show negative geotropism.
6. What happens at the synapse between two neurons?
   At the synapse, the electrical impulse triggers the release of chemical messengers called neurotransmitters, which cross the gap to initiate an electrical impulse in the next neuron.
7. Which hormone is responsible for the “fight or flight” response?
   Adrenaline, secreted by the adrenal glands, is responsible for the “fight or flight” response.
8. What is the role of insulin in the human body?
   Insulin regulates blood sugar levels by helping cells absorb glucose from the blood for energy.
9. What is a reflex action?
   A reflex action is an automatic, rapid, and involuntary response to a stimulus that minimizes damage to the body (e.g., pulling your hand away from a hot object).
10. Which plant hormone causes wilting of leaves?
    Abscisic acid is the plant hormone that promotes wilting of leaves by inhibiting growth and closing stomata during stress conditions.
