Question

Recent work in classification of life on Earth has shown that what were once called prokaryotes are much more diverse than ever 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 back 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 peptidoglycans
B) presence of chloroplasts for photosynthesis
C) contains a nucleoid rather than a nucleus
D) forms an outer capsule with slime coat

Answer 1

It's B

Step-by-step explanation:

We have the cell wall made up of peptidog like and we have the genetic material in the form of nuclear, so option b, chloro plast, which are required for photosynthesis, is irrelevant in case of procreat.
