Why True & False for Control and Coordination?
How this format sharpens your conceptual clarity
🔵 Control and Coordination explains how the body detects, processes, and responds to stimuli — the nervous and endocrine systems working together.
✅ T/F tests reflex arcs, types of neurons, plant hormones (tropisms), and the role of endocrine glands.
🎯 A reflex arc bypasses the brain — the spinal cord processes reflex actions directly, making the response faster.

Q 1
Reflex actions are automatic and involuntary responses to stimuli.
Q 2
The spinal cord controls voluntary actions in the human body.
Q 3
Plant hormones are essential for control and coordination in plants.
Q 4
Adrenaline increases heart rate during stressful situations.
Q 5
Tropic movements in plants are directional responses to stimuli.
Q 6
The cerebellum does not control posture and balance of the body.
Q 7
Human nervous system consists of brain, spinal cord, and nerves.
Q 8
Insulin hormone helps in increasing blood sugar level.
Q 9
Reflex arc includes receptor, sensory neuron, spinal cord, motor neuron and effector.
Q 10
Coordination in animals occurs only through the nervous system.
Q 11
The brain can be divided into forebrain, midbrain, and hindbrain.
Q 12
Gibberellin is a plant hormone responsible for cell elongation.
Q 13
Coordination is not required in unicellular organisms.
Q 14
Thyroid gland secretes hormone thyroxine controlling metabolism.
Q 15
The forebrain is mainly responsible for thinking and voluntary actions.
Q 16
Reflex actions are faster than voluntary actions.
Q 17
Auxin is a plant hormone that promotes cell division.
Q 18
Stomatal opening is controlled by brain signals.
Q 19
Coordination in plants is achieved through chemical means only.
Q 20
The pituitary gland is called the master gland.
Q 21
Dendrites receive electrical signals in a neuron.
Q 22
Phototropism is movement of plants in response to water.
Q 23
Hormones are produced in specialized cells and transported by blood.
Q 24
Sensory neurons carry impulses from receptors to the brain and spinal cord.
Q 25
Nerve impulses travel as electrical signals and not chemical signals.
Key Takeaways — Control and Coordination
Core facts for CBSE Boards & exams
1
Neuron = nerve cell; dendrites receive signals; axon transmits; synapse is the junction gap.
2
Reflex arc: receptor → sensory nerve → spinal cord → motor nerve → effector.
3
Brain regions: cerebrum (thinking), cerebellum (balance), medulla (involuntary actions).
4
Plant hormones: Auxin (phototropism), Gibberellin (elongation), Cytokinin (division), Abscisic acid (wilting).
5
Endocrine glands secrete hormones directly into blood (ductless glands).
6
Insulin (pancreas) lowers blood glucose; Adrenaline (adrenal) triggers fight-or-flight response.
