Class 10 Science — Chapter 6: Control and Coordination
66 practice questions · 22 Easy · 22 Medium · 22 Hard
Practise Class 10 Science Chapter 6, "Control and Coordination", with 66 NCERT-aligned multiple-choice questions. The set is split into 22 Easy, 22 Medium and 22 Hard questions, so you can warm up on the fundamentals and then push into the exam-level problems that separate top scorers in CBSE Board exams and the JEE & NEET foundation years.
"Control and Coordination" is one of the chapters where concept clarity across physics, chemistry and biology basics really pays off. Each MCQ on this chapter is timed and uses exam-grade marking (+2 correct, −1 wrong, 0 skipped), training the same accuracy-under-pressure that real papers demand. Every question carries a short explanation, so a wrong answer becomes a quick lesson rather than a dead end — the fastest way to close gaps before a test.
Use this chapter as targeted revision: attempt the Easy set first to confirm your basics on Control and Coordination, then move to Medium and Hard to test application and problem-solving. Your accuracy, streaks and XP save automatically, and the chapter feeds into your overall Class 10 Science mastery score. A few sample questions are shown below; sign in free to practise all 66.
Key concepts: Control and Coordination (Class 10 Science)
Organisms respond to stimuli through coordination — the nervous system and hormones in animals, and growth movements in plants.
- Neuron
- The nerve cell — dendrites receive the impulse, the axon carries it, and it passes to the next cell across a synapse.
- Reflex action
- A quick, automatic response to a stimulus, routed through the spinal cord via a reflex arc (it bypasses conscious thinking).
- Human brain
- Forebrain (thinking, senses), midbrain, and hindbrain — including the cerebellum (balance) and medulla (involuntary actions).
- Hormones (endocrine system)
- Chemical messengers such as adrenaline, insulin, thyroxine and growth hormone, regulated by feedback.
- Coordination in plants
- Tropic movements (phototropism, geotropism) are directional growth responses controlled by hormones like auxin; nastic movements are non-directional.
💡 Exam tips for Control and Coordination
- Reflex arcs work through the spinal cord for speed — the brain is informed afterwards.
- Iodine is needed to make thyroxine; its deficiency causes goitre.
Sample questions
The structural and functional unit of the nervous system is:
Neurons are the basic units.
A knee-jerk reflex is controlled by the:
Reflex arc passes through spinal cord, not brain.
Movement of a plant towards light is:
Phototropism: directional growth toward light (auxin-mediated).
