🔹 Control & Coordination
- Body activities ko regulate karna
- Stimulus ka sahi response dena
🧠 Nervous System (Animals)
- Neuron → dendrite (receive), axon (carry), synapse (gap)
- Reflex action → fast, automatic, spinal cord se
- Brain parts:
- Forebrain → thinking
- Midbrain → involuntary actions
- Cerebellum → balance & posture
- Medulla → heartbeat, breathing
⚡ Reflex Arc
Receptor → Sensory neuron → Spinal cord → Motor neuron → Muscle
🌱 Plants – Coordination
- 2 movements:
- Immediate (no growth) → Mimosa
- Growth based → tropism
🌿 Tropism
- Phototropism → light
- Geotropism → gravity
- Hydrotropism → water
- Chemotropism → chemicals
🌼 Plant Hormones
- Auxin → growth, bending
- Gibberellin → stem growth
- Cytokinin → cell division
- Abscisic acid → growth stop
🧪 Hormones in Animals
- Chemical messengers
- Blood ke through kaam
Important Hormones
- Thyroxin → metabolism
- Insulin → blood sugar
- Adrenaline → emergency
- Growth hormone → height
- Testosterone / Oestrogen → puberty
🔁 Feedback Mechanism
- Hormone zyada → secretion kam
- Hormone kam → secretion zyada

FAQs About Life Processes
Q1. What is control and coordination in living organisms?
Control and coordination refer to the ability of an organism to regulate its body
activities and respond properly to changes in the environment.
Q2. Which systems control and coordinate activities in animals?
In animals, control and coordination are carried out by the nervous system
and the endocrine (hormonal) system.
Q3. What is a reflex action?
A reflex action is a fast, automatic and involuntary response to a stimulus,
controlled mainly by the spinal cord.
Q4. What is a reflex arc?
A reflex arc is the pathway followed by a nerve impulse during a reflex action,
from receptor to effector.
Q5. Which part of the brain controls balance and posture?
The cerebellum controls balance, posture and precision of voluntary movements.
Q6. How do plants respond to stimuli without a nervous system?
Plants respond to stimuli using chemical coordination through plant hormones
and by changes in growth or water content of cells.
Q7. What is phototropism?
Phototropism is the directional growth of a plant part in response to light,
such as bending of shoots towards light.
Q8. Which hormone is responsible for bending of plants towards light?
Auxin hormone is responsible for cell elongation and bending of plants
towards light.
Q9. What is the role of adrenaline in humans?
Adrenaline prepares the body for emergency situations by increasing heart rate,
breathing rate and blood supply to muscles.
Q10. Why is insulin important for our body?
Insulin regulates blood sugar level in the body. Its deficiency leads to diabetes.
