Inspect cell cutaways and test the initial direction of water movement across a membrane.
Describe a structure and its function. Change one variable at a time in a fair comparison.
Compare enlarged plant and animal cutaways. Find shared structures, then identify features of this photosynthetic plant cell.
The wall lies outside the membrane. The large vacuole and chloroplasts distinguish this photosynthetic plant-cell example. Numbered labels match the structure list.

Enlarged schematic · Not to scaleDrag to orbit. Pinch or use the zoom buttons to enlarge. Two-finger drag pans on touch devices; right-drag pans with a mouse. Focus the 3D view and use arrow keys to rotate, +/− to zoom, Shift + arrow keys to pan, and Home to reset the camera. Every selectable structure is also a button below.
Select a structure in the model or the list to connect its position, shape and function.
The wall lies outside the membrane. The large vacuole and chloroplasts distinguish this photosynthetic plant-cell example.
Move through the structures in an order that connects their roles.
Original educational cutaways, enlarged and not to scale. The front and top of the plant boundary and the front half of the animal boundary are removed to expose the inside. Real cell shapes and organelle numbers vary. Colours are identifiers, and the small organelles are exaggerated. Only selected structures are shown. Chloroplasts occur in photosynthetic plant cells, not in every plant cell. Animal cells may have small vesicles/vacuoles; the model contrasts the large central vacuole of a typical mature plant cell. The root view is a representative non-photosynthetic plant-cell variant; plant cells vary by tissue and development. It reuses a simplified scaffold and does not depict a particular measured root cell.
This is a spatial learning model. Colour, transparency and layer separation help reveal relationships; they are not measurements.
Run a predicted experiment to activate process playback.
Cells contain structures with distinct roles; plant cells also respire.
Across a selectively permeable membrane, water tends towards the more concentrated solution when other conditions are equal.
A direction-only osmosis model with equal pressure and a water-permeable membrane; no active transport, equilibrium volume or rate law.
