💧 Water Potential Made Simple! 🌱
Remember the golden rule:
Water moves from higher (less negative) water potential → lower (more negative) water potential. 💦➡️🌱
🔹 Less negative = Higher Ψw = More free water
🔹 More negative = Lower Ψw = Less free water
🧠 Easy example: −0.2 MPa → −1.0 MPa
So, −0.2 MPa has the higher water potential.
Perfect for IGCSE/O Level Biology revision! 🧬📚

🧬 The Digestive System — From Food to Fuel! 🍎➡️💪
Ever wondered what each digestive organ actually does? 👀
This poster breaks it down organ by organ!
👄 Mouth → ingestion, physical digestion & starch digestion by amylase
💧 Salivary glands → release saliva containing amylase
🥣 Stomach → churns food & digests protein with protease in acidic conditions
🧪 Small intestine → completes chemical digestion using amylase, maltase, protease & lipase
🫀 Liver → produces bile & stores glycogen
🟢 Gall bladder → stores bile
🟡 Pancreas → releases alkaline pancreatic juice containing digestive enzymes
🌱 Ileum & colon → absorption
🚽 Re**um & a**s → egestion
