🌿 Quick Study Guide

  • ☀️ What is Photosynthesis? The process by which plants and other organisms convert light energy into chemical energy.
  • 💧 Reactants: Carbon dioxide ($CO_2$) and water ($H_2O$).
  • 🧪 Products: Glucose ($C_6H_{12}O_6$) and oxygen ($O_2$).
  • ⚙️ Formula: $6CO_2 + 6H_2O + Light Energy \rightarrow C_6H_{12}O_6 + 6O_2$
  • 📍 Where it Happens: Chloroplasts, which contain chlorophyll.
  • 🌳 Why it's Important: Produces oxygen for us to breathe and glucose for plant energy!
