🌿 Plant Cell Turgor Mechanics

Interactive 3D plant cell where adjusting external water concentration swells or shrinks the vacuole, pressing the cell membrane against the wall to generate or lose turgor pressure.

Biology3DModerate60 FPS💧 Water

An interactive 3D plant cell whose vacuole swells or shrinks as the surrounding water concentration changes, pressing the flexible membrane against the rigid cell wall to build or lose turgor pressure.

🔬 What It Demonstrates

Osmosis driven by a solute concentration gradient across the membrane: a dilute (hypotonic) external solution draws water in and inflates the vacuole against the wall, while a concentrated (hypertonic) solution pulls water out and causes plasmolysis.

🎮 How to Use

Drag the external solute concentration slider or pick a hypotonic/isotonic/hypertonic preset, adjust wall stiffness to see how it changes pressure build-up, and toggle the cutaway view to look inside the cell. Drag to rotate, scroll to zoom.

💡 Did You Know?

Turgor pressure alone — not rigid skeletons — is what keeps most herbaceous plants standing upright; lose enough of it and the same cells that held a leaf flat let it wilt within minutes.

⚙ Under the hood

Interactive 3D plant cell where adjusting external osmotic concentration shows how water flux across the membrane builds turgor pressure that stiffens the cell wall.
