(vi) Write the overall chemical equation for the above process.

Answer 1

• The process being studied here is photosynthesis.
  
• Photosynthesis is the process by which green plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of glucose.
  
• The overall chemical equation for the above process:-

$6C{O}_2+12H_{2}O\underset{\text{Sunlight}}{\overset{\text{Chlorophyll}}{\to }}{C}_6{H}_{12}{O}_6+6O_2+6H_{2}O$
