Osmosis Explained: Carrot Experiment Decoded

Water moves across semi-permeable membranes (carrot skin) from low-solute to high-solute areas.

• No water: Carrot loses moisture to dry air → shrivels.
• Pure water: Water enters carrot (higher internal solutes) → swells.
• Salt water: External solutes higher → water leaves carrot → shrinks.
