* Prokaryotes: These are single-celled organisms that lack a nucleus and other membrane-bound organelles.

* Bacteria are a type of prokaryote.

* Eukaryotes: These are organisms whose cells have a nucleus and other membrane-bound organelles.

* Plants and animals are both eukaryotes.

Here's a simple table to visualize:

| | Prokaryote | Eukaryote |

|---|---|---|

| Has a Nucleus | No | Yes |

| Has Membrane-Bound Organelles | No | Yes |

| Examples | Bacteria | Plants, Animals, Fungi, Protists |

So, to answer your question directly:

* Bacteria are prokaryotes.

* Plant cells are eukaryotes.

* Animal cells are eukaryotes.
