Drag cell shapes (the outlines) from the palette and drop them into the beaker's fluid. Calculate SA/V manually using the V and SA values provided for each shape. Click "Start / Resume All" to begin diffusion. All cells have Volume (V) = 100.

Cell Shapes

🧠 Test Your Understanding

1. If you have two cells with the same volume (V=100), which shape would absorb nutrients faster?

2. Why do most cells remain microscopic in size?

3. Based on your observations, which statement about diffusion time is correct?

4. Which real-world cell would likely have the highest SA/V ratio?

5. If a cube-shaped cell doubles its side length, what happens to its SA/V ratio?
