What are characteristics of archaebacteria?
Archaebacteria are unicellular prokaryotes that are the oldest living organisms on Earth. Some characteristics include survival in oxygen-free environments, being extremophiles and reproduction is asexual.
What are the characteristics of bacteria?
Characteristics of bacteria are prokaryotes, meaning they do not have membrane bound organelles, peptidoglycan cell wall, and asexual reproduction, meaning they only need themselves to multiply.
Do not have a nucleus?
Prokaryotes have no distinct nucleus.
What are cells without nucleoli called?
the answer is prokaryotes
Are all prokaryotes harmful?
No, the vast majority of prokaryotes are not harmful.
What characteristics do Monera and Prokaryocytes share?
Prokaryotes are part of the Monera kingdom. They have the same characteristics.
