Did you know that bacteria are a type of prokaryote?

Yeah, I learned that in biology class last week.

It's fascinating how they're so simple yet so essential for life.

Totally! I had no idea they could be so diverse.

Root Explanation

Prokaryote is formed from "pro-" (meaning before) and "karyon" (from Greek, meaning nucleus). The term refers to organisms that have no true nucleus, as they existed before the development of complex cells with nuclei.

Memory Tip

Think of 'before' ('pro-') and 'nucleus' ('karyon') to remember that a prokaryote is an organism that existed before the complex cell structure with a nucleus.
