Recent work in classification of life on Earth has shown that what were once called prokaryotes are much more diverse than ev
suspected. The prokaryotae are now divided into two domains, the Eubacteria and the Archaeabacteria, as different from each
other as either is from the Eukaryota. One organism, the blue-green algae or cyanobacteria, has left a fossil record that dates ba
nearly 3.5 billion years and is among the oldest fossils known. A few hundred years ago, this organism was classified as a plant
then more recently as a protist. Today it is classified in the kingdom Eubacteria. Which of these would NOT be evidence that
scientists compiled to place cyanobacteria in the Eubacteria.
A- presence of cell walls containing peptidolycans
B- presence of chloroplast for photosynthesis
C- contains a nucleoid rather than a nucleus
D- Forms in outer capsule with slime coat
