PROKARYOTIC VS. EUKARYOTIC
2
6 KINGDOM CLASSIFICATION
EUKARYOTES HAVE A NUCLEUS
PROKARYOTES NO NUCLEUS
3
Two Fundamentally Different Types of Cells
A PROKARYOTIC CELL
A EUKARYOTIC CELL
4
2 CELL TYPES

• PROKARYOTES HAS NO NUCLUES
• Pro before
• karyon kernel or nucleus
• THEY HAVE DNA!
• NO NUCLEUS JUST MEANS THAT THE DNA IS NOT
  ENCLOSED IN A MEMBRANE
• CALLED A NUCLEOID

COMPARISON

• Prokaryotes
• No real nucleus
• Less complex
• Ribosomes only
• One circular chromosome
• Unicellular or colonial
• Cell wall made of polysaccharide peptidoglycan
• Cell membrane
• Reproduce by binary fission
• Sexual reproduction by transfer of DNA fragments

• Eukaryotes
• True Nucleus
• More complex
• Many organelles
• Many Linear chromosomes
• Unicellular or multicellular
• Cell wall (plants fungus) not made of
  peptidoglycan
• Cell membrane (all)
• Reproduce by mitosis
• Sexual reproduction by meiosis
