What is prokaryotic cells?Show answer
Prokaryotes (from the Greek for "before nucleus") are typically 1 to 5 micrometres in diameter. They include all Bacteria and Archaea.
What is eukaryotic cells?Show answer
Eukaryotes (from the Greek for "true nucleus") are typically 10 to 100 micrometres in diameter. They include all animals, plants, fungi, and protists.
What is saying prokaryotes "have no DNA"?Show answer
They have DNA; it just is not enclosed in a nucleus.
What is saying eukaryotes are always larger?Show answer
Almost always, but some large bacteria (such as Thiomargarita namibiensis) reach 0.75 mm. Use the structural definition, not the size.
What is saying "no organelles in prokaryotes"?Show answer
Prokaryotes have ribosomes, which are organelles in the broad sense; they just have no membrane-bound organelles.
What is calling plasmids "small organelles"?Show answer
Plasmids are small circular DNA molecules, not organelles.
