2 Two Basic Types of Cells Prokaryotic Cells And Eurkaryotic Cells

3 Two Types of Cells ALL CELLS HAVE DNA but: Prokaryotic Cells – do NOT have a nucleus around the DNA (bacteria) Eukaryotic Cells- DO HAVE a nucleus that surrounds the DNA 2 Bacterial Cell

4 How are Prokaryotic and Eukaryotic Cells Alike? Both cell types have: A Cell membrane –to surround cell DNA – to control activities Ribosomes (for making proteins) Cytoplasm – to hold cell parts

5 Prokaryotes 4 Oldest cell on earth Name means” :“before kernal Extremely small, 10X smaller than plant and animal cells

6 Prokaryotic Cell Differences No nucleus No membrane-covered organelles Circular DNA

7 Examples of Prokaryotic Cells Example Organisms: Eubacteria (common) Archaebacteria (live in extreme places) (The two look similar but differ in chemical make-up) EubacteriaArchaebacteria live in extreme places like hot springs in Yellowstone National Park

8 Eukaryotic Cell Cells have a Nucleus Name means: “true kernal” larger than prokaryotic cells 7

9 Eukaryotic Cell Differences Has a nucleus Has membrane-covered organelles Linear DNA

10 Examples of Eukaryotic Cells 9 Plant Cell Animal Cell Animals Plants Fungi –mushrooms, yeast Protists –amoeba, algae
