Photosynthesis in Higher Plants - Lecture by Vipin Kumar Sharma

Introduction

• Speaker: Vipin Kumar Sharma
• Topic: Photosynthesis in higher plants
• Objective: Understanding the outline and basic concepts of photosynthesis
• Approach: Objective understanding, NCERT-based exploration, concise revision

Definition of Photosynthesis

• Terminology: Photo (Sunlight) + Synthesis (Making)
• Process: Conversion of light energy into chemical energy
• Equation:
  • General: CO2 + H2O + Light energy → C6H12O6 + O2
  • Balanced: 6CO2 + 12H2O + Light energy → C6H12O6 + 6H2O + 6O2
• Importance: Produces organic food (glucose) using inorganic resources
• Two definitions:
  • Synthesis of organic food by using inorganic resources
  • Conversion of light energy into chemical energy

Importance of Photosynthesis

• Food Production:
  • Primary function, producing glucose that can be stored or utilized by plants
  • Secondary function, supporting ecosystems by providing oxygen
  • Plants
