Subject: Why is bacteria genome so small?

This question deals with bacterial genomic DNA! I was wondering why bacteria 
are so small? Does their size have anything to do with their genome? I just 
found out that bacteria do not have any introns compared to higher organisms, 
could this be due to their small size. Could it be that, they shed their 
introns throughout evolution, since they did not have room to accomodate this 
big volume of material, compared to human beings or plants? Or is it the other 
way around, that thoughout evolution, they found a way to accomodate their 
small volume of genetic material. I hope that my question makes senses. I'm 
just trying to find out whether there is a relationship between the genome of 
bacteria and their size.
Thank you.
