3D Cell & Organelle Explorer: free online, no upload
The 3D Cell & Organelle Explorer is a free, interactive WebGL model of an animal cell. Search for an organelle — mitochondria, nucleus, Golgi apparatus, endoplasmic reticulum and more — zoom straight to it through the hierarchy tree, slice the cell with a cross-section view, and read a short, exam-ready description of each structure's function. Everything renders live in your browser, with no upload and no account.
