Cell Basics

Two main types of cells:

1.

Prokaryotes 2. Eukaryotes

Cell Basics

​Nucleus

​No Nucleus

Prokaryotic Cells: Do not have a nucleus and do not have membrane bound organelles. (That does not mean they do not have organelles at all) They are also much smaller than eukaryotic cells.

Cell Basics

Eukaryotic Cells: Do have a nucleus and do have membrane bound organelles. They are 100 times larger than prokaryotic cells.

Multiple Choice

What is the main difference between prokaryotes and eukaryotes?

• Prokaryotes have a nucleus

• Eukaryotes have a nucleus

• They are the same! DUMBO

• Prokaryotes evolved before Eukaryotes

Organisms made of prokaryotic cells are called prokaryotes. They are unicellular, which means they are made of one cell. Scientist believe that prokaryotes are the oldest living things on Earth.

Cell Basics

Examples of Prokaryotes are:

1.

Bacteria

2.

Archaea

Fill in the Blanks

True or False. All prokaryotes are unicellular.

Bacteria are prokaryotes that can be pyramid, cubic, or rod shaped. Some can perform photosynthesis.

Cell Basics

Archaea are prokaryotes that live in extreme environments like thermal vents and acid pools.

Organisms made of eukaryotic cells are called eukaryotes. They can be unicellular or multicellular (made of many cells). Unicellular eukaryotes are classified as protist or some fungi.
