Cellular respiration and photosynthesis are two important processes in biology that do opposite things. Let’s break them down simply:

Photosynthesis:

• Where it happens: In plants, algae, and some bacteria.
• What it does: Changes light energy from the sun into chemical energy, which we know as glucose (a type of sugar).
• Showing it in a simple equation:
  Carbon dioxide + Water + Light energy → Glucose + Oxygen
  (6CO2 + 6H2O + light energy → C6H12O6 + 6O2)

Cellular Respiration:

• Where it happens: In all living things, including plants and animals.
• What it does: Breaks down glucose to release energy that the organisms can use.
• Showing it in a simple equation:
  Glucose + Oxygen → Carbon dioxide + Water + Energy
  (C6H12O6 + 6O2 → 6CO2 + 6H2O + energy)

To sum it up, photosynthesis creates energy-packed sugars, while cellular respiration uses those sugars to produce energy.
