Why does the evolution of bacterial cells go faster than eukaryotic cells.

The reproduction rate of bacteria of their own kind, like prokaryotes, is incomparably higher than that of all other inhabitants of the planet. The evolutionary adaptation of any species to changing living conditions requires a change of many generations. This process, which gives noticeable results for multicellular organisms only after tens or hundreds of years or centuries, passes in bacteria in a matter of days or even hours.
