Introduction (परिचय)

Life processes are the basic activities that keep an organism alive.
जीवन प्रक्रियाएँ वे क्रियाएँ हैं जो किसी जीव को जीवित बनाए रखती हैं।

Examples:

• Nutrition (पोषण)
• Respiration (श्वसन)
• Transportation (परिवहन)
• Excretion (उत्सर्जन)

Without these processes, no living organism can survive.

Nutrition (पोषण)

Definition:

Nutrition is the process of taking food and using it for energy, growth and repair.
पोषण वह प्रक्रिया है जिसमें जीव भोजन ग्रहण करके ऊर्जा और विकास के लिए उपयोग करता है।

Types of Nutrition:

1. Autotrophic Nutrition (स्वपोषी पोषण)

• Organisms make their own food.
• Example: Plants

Process: Photosynthesis (प्रकाश संश्लेषण)

6CO₂ + 6H₂O {sunlight, chlorophyll}→ C₆H₁₂O₆ + 6O₂

Plants use sunlight, carbon dioxide, and water to make glucose.

2. Heterotrophic Nutrition (परपोषी पोषण)

• Organisms depend on others for food.
• Example: Humans, animals

🔹 Types:

• Holozoic (मानव)
• Saprophytic (fungi)
• Parasitic (tapeworm)

Human Digestive System (मानव पाचन तंत्र)

Main Parts:

• Mouth (मुख)
• Oesophagus (ग्रासनली)
• Stomach (आमाशय)
• Small intestine (छोटी आंत)
• Large intestine (बड़ी आंत)

Example:
Food is broken into glucose → gives energy

Respiration (श्वसन)

Definition:

Respiration is the process of breaking down food to release energy.
श्वसन वह प्रक्रिया है जिसमें भोजन से ऊर्जा प्राप्त होती है।

Types:

1. Aerobic Respiration (ऑक्सीजन के साथ)

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + Energy

Occurs in the presence of oxygen

2. Anaerobic Respiration (ऑक्सीजन के बिना)

• Occurs without oxygen
• Example: Yeast

Produces less energy

Human Respiratory System

Parts:

• Nose (नाक)
• Trachea (श्वासनली)
• Lungs (फेफड़े)
• Diaphragm

Oxygen enters → Carbon dioxide exits

Transportation (परिवहन)

Definition:

Transportation is the movement of substances inside the body.
परिवहन वह प्रक्रिया है जिसमें पदार्थ शरीर में एक स्थान से दूसरे स्थान तक पहुँचते हैं।

In Plants:

Two main tissues:

• Xylem → water transport
• Phloem → food transport

Example:
Roots absorb water → leaves receive it

In Humans:

Circulatory System (रक्त परिसंचरण तंत्र)

Parts:

• Heart (हृदय)
• Blood (रक्त)
• Blood vessels (रक्त वाहिकाएँ)

Heart Function:

• Pumps blood continuously

Blood Components:

• RBC (oxygen transport)
• WBC (fight infection)
• Platelets (clotting)

Excretion (उत्सर्जन)

Definition:

Excretion is the removal of waste substances from the body.
उत्सर्जन वह प्रक्रिया है जिसमें शरीर से अपशिष्ट पदार्थ बाहर निकाले जाते हैं।

Human Excretory System

Parts:

• Kidneys (गुर्दे)
• Ureters
• Urinary bladder
• Urethra

Kidneys filter blood and form urine.

Excretion in Plants:

• Oxygen release
• Shedding leaves
• Storage in vacuoles

Control & Coordination Link (Extra Concept)

All life processes are controlled by:

• Nervous system (तंत्रिका तंत्र)
• Hormones (हार्मोन)

Key Differences (Important for Exam)

Process	Function
Nutrition	Food intake
Respiration	Energy release
Transportation	Movement of materials
Excretion	Removal of waste

Class 10 Life Processes Case Study Questions: Important Points to Remember

✔ Plants prepare their own food
✔ Humans depend on plants/animals
✔ Oxygen is essential for respiration
✔ Blood transports nutrients and gases
✔ Kidneys filter waste from blood

Class 10 Life Processes Case Study Questions: Conclusion

Life processes are essential for survival.
Without nutrition, respiration, transportation, and excretion, life cannot exist.

👉 Understanding these helps in:
