Photosynthesis Process Equation and Importance Full Concept
🌱 1. What is Photosynthesis?
Photosynthesis is a biological process in green plants where they use sunlight to make food from carbon dioxide and water.
🧠 Definition:
Photosynthesis is the process by which green plants manufacture glucose (food) using carbon dioxide, water, and sunlight in the presence of chlorophyll.
🟩 By-product: Oxygen gas (O₂)
🌞 2. Why is Photosynthesis Important?
- Produces oxygen necessary for human and animal life
- Maintains carbon dioxide-oxygen balance in the atmosphere
- Basis of the food chain
- Removes CO₂, reducing greenhouse effect
Without photosynthesis, there would be no life on Earth.
🌿 3. Where Does Photosynthesis Occur?
Photosynthesis occurs in the chloroplasts found in green parts of plants like:
- Leaves (main site)
- Green stems
- Sepals and sometimes in petioles
✅ Use a Chloroplast Structure Model for better understanding –
💧 4. Raw Materials Needed
Plants require:
- Carbon Dioxide (CO₂) – from air, through stomata
- Water (H₂O) – absorbed by roots from the soil
- Sunlight – source of energy
- Chlorophyll – the green pigment
🧪 5. Photosynthesis Chemical Equation
Balanced chemical equation:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
(in presence of sunlight and chlorophyll)
- CO₂ = carbon dioxide
- H₂O = water
- C₆H₁₂O₆ = glucose
- O₂ = oxygen

🔬 6. Steps Involved in Photosynthesis
Photosynthesis happens in two main stages:
A. Light Reaction (Occurs in the grana)
- Requires light
- Water is split into hydrogen and oxygen (photolysis)
- ATP and NADPH are formed
B. Dark Reaction / Calvin Cycle (Occurs in stroma)
- Does not need direct light
- Uses ATP + NADPH + CO₂ to form glucose
✅ Use Light vs Dark Reaction Comparison Chart for clarity –
🧬 7. Structure of Chloroplast – Photosynthesis Site
The chloroplast is the organelle where photosynthesis occurs.
Parts:
- Outer and inner membrane
- Thylakoid (contains chlorophyll)
- Grana (stacks of thylakoid)
- Stroma (fluid-filled)

🔦 8. Light vs Dark Reactions – In Detail
Feature | Light Reaction | Dark Reaction |
---|---|---|
Location | Grana | Stroma |
Requires Light? | Yes | No |
Input | H₂O, sunlight | CO₂, ATP, NADPH |
Output | O₂, ATP, NADPH | Glucose (C₆H₁₂O₆) |
Process | Photolysis | Carbon Fixation |
🧯 9. Factors Affecting Photosynthesis
Several external and internal factors affect photosynthesis rate:
- 🌞 Light intensity
- 🌡️ Temperature
- 🌫️ CO₂ concentration
- 🌊 Water availability
- 🌿 Chlorophyll concentration

🧫 10. Types of Photosynthesis
- C3 Photosynthesis
- Common in all plants like wheat and rice
- First stable compound is a 3-carbon molecule
- C4 Photosynthesis
- Found in maize, sugarcane
- Adapted for hot climates
- CAM Photosynthesis
- Found in desert plants like cactus
- Saves water by opening stomata at night
⚖️ 11. Photosynthesis vs Respiration
Feature | Photosynthesis | Respiration |
---|---|---|
Happens in | Green parts | All living cells |
Gas Used | CO₂ | O₂ |
Gas Released | O₂ | CO₂ |
Energy | Consumes light energy | Releases ATP |
Time | Day only | 24 hours |
🧪 12. Experiments to Show Photosynthesis
A. Oxygen is produced during photosynthesis
→ Use Hydrilla Experiment

❌ 14. Common Misconceptions
- Photosynthesis happens only in sunlight – ❌
- Only leaves do photosynthesis – ❌ (some stems can too)
- Plants don’t respire – ❌ (they do!)
✍️ 15. Practice Questions for Class 10
- What is the balanced chemical equation for photosynthesis?
- Differentiate between light and dark reactions.
- Why is chlorophyll necessary for photosynthesis?
- How does carbon dioxide enter the leaves?
- What are the raw materials for photosynthesis?
📘 16. NCERT Exercise Questions – Photosynthesis Answers
Q. What are the end products of photosynthesis?
Ans. Glucose and oxygen are the end products.
Q. How do plants obtain carbon dioxide?
Ans. From the air, through tiny pores called stomata.
Q. Explain the process of photosynthesis in detail.
Ans. In presence of sunlight and chlorophyll, plants take in carbon dioxide and water and convert them into glucose. Oxygen is released as a by-product.
