Eukaryotic and Prokaryotic cells
SIMILARITIES;
- They are both membrane bound.
- They both have DNA as their genetic material
- They both have ribosomes .
- They have similar basic metabolism .
- They are both amazingly diverse in forms
DIFERENCES;
- eukaryotes have a nucleus, while prokaryotes do not
- eukaryotes have membrane-bound organelles, while prokaryotes do not. The organelles of eukaryotes allow them to exhibit much higher levels of intracellular division of labor than is possible in prokaryotic cells.
- Eukaryotic cells are, on average, ten times the size of prokaryotic cells.
- The DNA of eukaryotes is much more complex and therefore much more extnsive than the DNA of prokaryotes.
- Prokaryotes have a cell wall composed of peptidoglycan, a single large polymer of amino acids and sugar . Many types of eukaryotic cells also have cell walls, but none made of peptidoglycan.
- The DNA of prokaryotes floats freely around the cell; the DNA of eukaryotes is held within its nucleus and associated with histones (proteins)
- Eukaryotes undergo mitosis; prokaryotes divide by binary fission (simple cell division)
