B.5B Prokaryotic Eukaryotic

Which is not a characteristic of prokaryotic cells?

• Have no nucleus

• Complex structure

• Single Celled

• Circular DNA

All of the following characteristics are shared by both prokaryotic and eukaryotic cells except

• Has cytoplasm

• Genetic material contained in membrane bound organelle

• Cell Membrane

• Contains ribosomes

The endosymbiotic theory states that eukaryotic cells evolved when

• an existing cell took in nutrients from the environment, gradually increasing in size and function

• an existing cell became infected with a virus, which then mutated to form organelles

• an existing cell divided but stayed attached to the new cell, which then became specialized

• an existing cell ingested another cell, which survived and took on specialized functions
