Front

What kingdom do living things with pseudopeptidoglycan belong to?

Back

Archaebacteria

Front

According to the endosymbiotic theory, how did early eukaryotes originate?

Back

Small bacteria (prokaryotes) were engulfed by other prokaryotes, forming symbiotic relationships that evolved into eukaryotic cells.

Front

Which taxon has the most variety of organisms?

Back

Front

What is NOT evidence of the Endosymbiotic Theory?

Back

Mitochondria and chloroplast can now live independently outside of the cell.

Front

What question helps determine if a unicellular prokaryotic organism is eubacteria or archaebacteria?

Back

Does the organism live in an extreme environment?

Front

What is the primary difference between eubacteria and archaebacteria?

Back

Eubacteria are found in more common environments, while archaebacteria often live in extreme environments.

Front

What is pseudopeptidoglycan?

Back

A polymer similar to peptidoglycan found in the cell walls of some archaebacteria.

Front

What is the significance of mitochondria and chloroplasts having their own DNA?

Back

It supports the endosymbiotic theory, suggesting they were once independent prokaryotic organisms.

Front

What are the main characteristics of prokaryotic cells?

Back

They lack a nucleus, are unicellular, and have a simple structure.

Front

What is the role of a cell wall in bacteria?

Back

It provides structure and protection to the cell.
