🌿 Leaf Adaptations for Photosynthesis 🌞
Leaves are specially designed to make the most of sunlight and CO₂. Did you know:
• Broad, thin surface → maximizes light absorption
• Upper epidermis & cuticle → reduces water loss
• Palisade mesophyll cells → packed with chloroplasts for efficient photosynthesis
• Spongy mesophyll & air spaces → allow easy gas exchange
• Veins → transport water and sugars

🚨 Struggling with Human Nutrition in IGCSE Biology (0610)?

Here’s a one-page summary of the Digestive System — straight from the syllabus ✅

🦷 Mouth → Mechanical & chemical digestion
🧪 Stomach → Proteins digested by pepsin + HCl
🌱 Small intestine → Enzymes, bile, villi absorption
💧 Large intestine → Water absorbed
🚪 A**s → Egestion of undigested food

📌 Save this for quick revision — and never confuse digestion, absorption, and egestion again!
