They utilize what
they have but both are efficient its just that eukaryotic organisms have
a better system for surivival and storage than prokaryotic which in
contrast needs a lot of sustained energy.
There are differences
between Eukaryotic and Prokaryotic cells. This difference is considered
to be the most important distinction between groups of organisms. A
Prokaryotic cell does not contain a nucleus. It only contains one
chromosome and is a single-celled organism. It was the only form of life
on earth for millions of years. Examples of a Prokaryotic cell are the
different types of bacteria present today.
A Eukaryotic cell contains a nucleus; more than one chromosome and is typically a multi-celled organism. Both plant and animal cells are eukaryotic cells.
