Is a cell of animals prokaryotes

Prokaryotes are single celled organisms that do not have a nucleus, mitochondria or any other membrane bound organelles. In other words neither their DNA, nor any of their other sites of metabolic activity, are collected together in a discrete membrane enclosed area. Instead everything is openly accessible within the cell, some free floating, some bound to the walls of the cell membrane, it is this lack of membrane-bound organelles which separates them from the Eukaryotes. Some bacteria have internal membranes, invaginations of the cell membrane as sites of metabolic activity, however these membranes do not enclose a separate area of the cytoplasm.

Here's a trick I got taught to remember which way round they went
It involves what the words actually mean

Eu (true) karyote (nucleus)
Pro (before) karyote (nucleus)

Eu rhymes with true so it's even easier to remember
