  1. BACTERIA Source:Bacteria.wikipedia,the free encyclopedia

  2. Are bacteria larger or smaller than eukaryotic cells? smaller!

  3. Look at these photos and say which cell is larger. Notice the scale. E.coli Paramecium sp 2 µm 50µm Which is the bacteria, E.coli or Paramecium? Why? E. coli Pictures source: oldearth.wordpress.com/microbios-en-accion;www5.pbrc.hawaii.edu/microangela/param.htm

  4. And now, which cell is larger? Notice the scale. Eukaryotic cell Prokaryotic cell 2 µm 2 µm Pictures source:Bacteria.wikipedia,the free encyclopedia;www.biochemistry.blogspot.com

  5. How many times smaller is this bacterium than the eukaryotic cell? Source:www.star.ucl.ac.uk

  6. So, one difference between bacteria and eukaryotic cells is size: Cell Size Bacteria Eukaryota smaller larger More differences? Yes, the nucleus!

  7. Bacteria have prokaryotic cells. This means that they don't have nuclear membrane. Prokaryotic cell Eukaryotic cell DNA 2 µm 2 µm nuclear membrane Pictures source:Bacteria.wikipedia,the free encyclopedia;www.biochemistry.blogspot.com

  8. So, what is the difference between prokaryotic and eukaryotic cells? Cell Size Nucleus Prokaryotic Eukaryotic Small No nuclear membrane Big Nuclear membrane More differences? Yes, the complexity.

  9. Look inside of these cells. Which is more complex? 2 µm 2 µm Photo source: wikipedia, the free encyclopedia

  10. Then, the differences between prokaryotic and eukaryotic cells are: ? ? ? Size Nucleus Complexity Cell Prokaryotic Eukaryotic
