2. INTRODUCTION
A eukaryote is an organism whose cells contain complex
structures enclosed within membranes.
Eukaryotic cells have an organized nucleus with a
nuclear envelope. They have a "brain" for the cell. They
have a discreet area where they keep their DNA. It is
also said that they have a "true nucleus."
Although limited in size, eukaryotic cells can get very
large. There are even some extreme examples called
plasmodial slime molds that can be a meter wide.
Eukaryotic cells have organelles and organized DNA so,
they are able to create parts. One example is the
flagellum (a tail-like structure to help it move).

EUKARYOTES:
They are the cells that have helped organisms advance to new levels
of specialization beyond imagination. You wouldn't be here if
eukaryotic cells did not exist.
