tMoL: Big Cell, Little Cell

I’m writing this as a homage to one of my closest friends on the blogosphere. The every wonderful LabRat has finally ended her fraught relationship with scientific research and is throwing herself wholeheartedly into science writing. Whilst I am hugely envious, I wish her all the best and hope she will remember me when she is rich and famous. Look out for her in future publications.
By way of background; Lab Rat has always had a fixation with the simpler things in life, by which I mean bacteria.

False colour E. coli, bacterial/prokaryotic cells.
All living organisms are made up of cells individual living units which are relatively self-supporting and capable of total self-replication, although this is complicated by the intricate interactions between different cells in larger organisms. Whilst larger creatures, like humans are made up of billions of cells, the vast majority of life on Earth exists as single celled microorganisms that cannot be observed with the naked eye.
Cells fall into two main groups, larger and more complex organisms, plants, animals and fungi are called eukaryotes (that’s us humans too) and have much more intricate cellular structures. The earliest forms of life, with the simplest cells are called prokaryotes, which include bacteria.
