Question

Most primitive organisms among the following are
a. Monerans
b. Protists
c. Fungi
d. Algae

Answer 1

The current "Procaryotic dogma" claims that procaryotes are primitive. Since the ancestor of Archaea was most probably a hyperthermophile, and since bacteria too might have originated from hyperthermophiles, the procaryotic dogma has been recently connected to the hot origin of life hypothesis
that means that monerans are the most primitive organism

Answer 2

Most primitive organisms among the following are Monerans.

● Extra information -

• They are unicellular and have prokaryotic cell.
• They are believed to be first to evolve.
• In monerans, membrane bound organelles are absent.
• They don't have definite nucleus & genetic material is freely moving in cell cytoplasm.
• For example, E.coli, H.pylori, S.aureus, N.meningitidis, etc.

Thanks dear. Hope this helps you...
