This document summarizes the key differences between prokaryotic and eukaryotic cells. Prokaryotic cells, such as those found in bacteria, lack a membrane-bound nucleus and organelles. In contrast, eukaryotic cells, which make up plants and animals, have a well-defined nucleus enclosed in a membrane and various membrane-bound organelles. The document also notes that prokaryotes have circular DNA floating in the cytoplasm while eukaryotes have linear DNA enclosed within the nucleus.

2. Prokaryotic and Eukaryotic cell
• Prokaryotic cell
• Cell which lack a well defined nucleus is called
Prokaryotic cell e.g. Bacterial cell & blue green algae
• Eukaryotic cell
• Cell having a well defined nucleus is called
eukaryotic cell e.g. Plants, animals cells.
• Prokaryote
• Organism made up of prokaryotic cell are called
prokaryote e.g. Bacterial cell & blue green algae
• Eukaryote
• Organism consisting of eukaryotic cells are called
Eukaryote e.g. Plants and animals

4. Prokaryotes and eukaryotes
Prokaryotes
• lack a membrane
bounded Organelles
• Ribosomes are the only
organelles 70S
• Genetic material floats
in the cytoplasm (DNA
and RNA)
Eukaryotes
• Posses membrane
bounded organelles
• Multiple organelles
including ribosomes
80S
• Membrane covered
Genetic material

5. Prokaryotes and eukaryotes
Prokaryotes
• Circular DNA
• Unicellular
• Cells are smaller in size
• Has larger number of
organisms
• Appeared 4 billion years
ago
Eukaryotes
• Linear DNA
• May be multicellular or
unicellular
• Cells are larger in size
• Has smaller number of
organisms
• Appeared 1 billion years
ago
