Cells

Every living thing is built from cells, and most of them are far too small to see. This course starts with the people who first saw cells, measures them in micrometers, takes an animal cell and a plant cell apart in 3D, and ends with how one cell becomes two. Pick an organelle in the model, cut the cell open and read the scale bar as you zoom.
