My professor has been lecturing on formyl-Methionine... I understand that prokaryotes use f-MET as the beginning of their protein synthesis, but I guess I need to know why? Why do they need to distinguish from a beginning MET codon from a MET codon downstream?

In order to make sure that the MET has not been labelled with other radicals.

Why do prokaryotes use formyl-methionine when eukaryotes use methionine for protein synthesis?

It's just the codon that is recognized by the translational machinary. It's just what nature chose to be the first codon. Many times, the methionine is even cut off of the protein. Also, AUG is the only codon more Methionine
