The Domain Eukaryota

What do trees, monkeys, plankton and mushrooms have in common? They are all members of the Eukaryota domain! You are a member of the Eukaryota domain too! Plants, animals, protists, and fungi, are all members of the domain.

These groups might seem pretty different, and they are, but they all have a few key aspects in common including their unique cells that are called eukaryotic. All members of the domain Euraryota have eukaryotic cells. And it is the only domain whose members have this cell type. Eukaryotic cells contain a special part called a nucleus that contains genetic material within chromosomes.
