Photosynthesis Quiz with Answers for 8th Grade Science Prep

🌿 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!
