Definition

An organism made up of one or more cells that have a nucleus and other structures enclosed within membranes.

Example

Humans are eukaryotes because our cells have a nucleus.

Conversation

Did you know that a eukaryote has a nucleus in its cells?

Really? I thought all cells were pretty much the same.

Nope! Eukaryotes are more complex than prokaryotes, like bacteria.

That’s interesting! I want to learn more about how they function.

Root Explanation

Eukaryote → It is formed from "eu-" (meaning good or true) and "karyon" (meaning nucleus in Greek). The word "eukaryote" refers to organisms whose cells have a true nucleus enclosed within membranes, distinguishing them from prokaryotes, which lack a defined nucleus.

Memory Tip

Think of 'eu-' meaning 'good' or 'true' and 'karyon' meaning 'nucleus' — this helps you remember that a eukaryote is an organism with a true nucleus.
