This document summarizes the key differences between prokaryotic and eukaryotic cells. It notes that prokaryotes are simpler cells that lack a nucleus and membrane-bound organelles, having only a cell membrane and cell wall. In contrast, eukaryotes are more complex cells that have a nucleus and various membrane-bound organelles to carry out specialized functions. Examples given are that all bacteria are prokaryotes, while plants and animals are eukaryotes. Both prokaryotes and eukaryotes are surrounded by a cell membrane and contain DNA.

1. Prokaryotes vs Eukaryotes

2. Cells! All living things are made up of cells . Cells are the basic unit of structure and function for living organisms. Cells are the smallest part of a living thing that is still considered living.

3. Some living things are made up of a lot of cells (multicellular), while others are only made of one cell (unicellular). Cells are composed of parts that each perform a different and important function . Can you think of anything else that is composed of parts that each perform a different function?

4. Types of Cells We have already discussed the two major types of cells: Prokaryotes Eukaryotes Today we are going to talk about them in more detail.

5. Prokaryote

6. Prokaryotes Prokaryotes have NO nucleus or membrane bound organelles. They are simple and small. Prokaryotes are surrounded by a cell membrane and a cell wall. Prokaryotes have circular DNA , but it is not inside a nucleus. Prokaryotes have a flagella for movement. All bacteria are Prokaryotes.

7. Eukaryote

8. Eukaryotes Eukaryotes have a nucleus and lots of membrane bound organelles. Each organelle has a specific job . Eukaryotes are much more complex and larger than prokaryotes. All Eukaryotes are surrounded by a cell membrane. Plant cells also have a cell wall . Eukaryotes have DNA that is housed inside a nucleus (central control center). Plants and animals are Eukaryotes.

9. What do Prokaryotes and Eukaryotes have in common?
