Absorption and Action Spectra

🌱 How Do Plants Absorb Light for Photosynthesis? 🌱 In this IB Biology video, we explore how light, plant pigments, and chromatography play a crucial role in photosynthesis. You'll learn about: ✅ The visible light spectrum and how different wavelengths affect plant growth 🌈 ✅ The absorption spectrum vs. action spectrum – What colors do plants really use? ✅ The role of pigments like chlorophyll a, chlorophyll b, carotenoids, and xanthophylls ✅ How to separate plant pigments using paper chromatography 🧪 ✅ How to calculate Rf values for different pigments This video is perfect for IB Biology students, AP Biology students, and anyone interested in plant science! 🌿💡 🔬 Want more IB Biology content?
