3. Fungi
Eukaryotic cell types
• Can be found in …
4. Protists - unicellular organisms ( ONE CELL)
Prokaryotic Cells
• Can be found in.. 1. Bacteria
Prokaryotic Cells
• Can be found in.. 2. Archaebacteria – bacteria that can be found in extreme environments. Genetically different from bacteria.
Differences
Prokaryotic Cells • No Nucleus: DNA is free
floating in the cell. • Small and simple organisms.
Eukaryotic Cells • Have a true nucleus and
membrane bound organelles.
• Are larger and more complex than prokaryotes
Similarities
Prokaryotic Cells and Eukaryotic Cells • Cell membrane • DNA • Cytoplasm • Ribosomes • Both meet ALL 8
characteristics of life
