Question: Hi Carolyn, what would happen if cells never got discovered?

Well if we had never discovered cells, it would have changed human history! Understanding that living organisms (other than viruses) are made of cells is central to a lot of what we know. Knowing about cells is important for inventing drugs (which target specific parts of cellular machinery) or vaccines (trying to coax different responses from different cells).

The British Society for Cell Biology have a nice post about this: http://bscb.org/learning-resources/softcell-e-learning/why-cell-biology-is-so-important/

I have always found cell biology much more interesting than molecular biology or chemistry because it deals with things at a level that is a little easier to understand… you can see cells pretty easily down a microscope if you want to!
