Question

Both bacteria and amoeba are unicellular organisms. Bacteria are considered to be prokaryotes, whereas amoebas are considered to be eukaryotes. How will you justify this reasoning? Though both are unicellular, bacteria possess a well-defined nucleus without a nucleolus. Amoebas possesses a nucleus with a nucleolus, but no nuclear membrane. Though both are unicellular, bacteria possess a well-defined nucleus and all essential cell organelles, whereas amoebas do not possess a nucleus or cell organelles, except ribosomes. Though both are unicellular, bacteria doesn’t possess a nucleus or cell organelles, except ribosomes, whereas amoebas possess a well-defined nucleus and all essential cell organelles.

Answer 1

Though both are unicellular, bacteria doesn’t possess a nucleus or cell organelles, except ribosomes, whereas amoebas possess a well-defined nucleus and all essential cell organelles.

Both bacteria and amoeba are single-celled organisms. They both have ribosomes.

Bacteria is a prokaryote. It lacks membrane-bound nucleus, mitochondria, chloroplasts or any membrane-bound organelles.

Amoeba is a eukaryote. It has a "true" nucleus containing its DNA and organelles which is responsible for energy production and protein transport.
