Study Notes

Photosynthesis Overview

  • Photosynthesis is a process that converts light energy into chemical energy.
  • Occurs within chloroplasts of plant cells.
  • Enzymes and chlorophyll accelerate the process.
  • ATP plays a role in absorbing light during photosynthesis.
  • Produces oxygen as a byproduct.
  • Creates food (glucose) for the plant.
  • Glucose and oxygen are the products of photosynthesis.
  • Uses sunlight, carbon dioxide, and water to produce energy-rich organic molecules (sugar/glucose) and oxygen.

Photosynthesis Details

  • Photosynthesis uses light energy to create chemical energy.
  • Water, carbon dioxide, and light energy combine to produce oxygen and glucose (sugar).
  • The chemical formula represents the process: Light energy + water + carbon dioxide → oxygen + sugar.
