What is inside a single living cell?

You are built from somewhere around 30 trillion cells, each one far too small to see. It would be easy to imagine a cell is just a tiny blob of jelly. But zoom right in and a single cell turns out to be astonishingly busy, packed with separate parts, each doing its own job, like a whole working city squeezed into a dot you could never spot with your eyes. So what is actually going on in there?
