Question

A unicellular microorganism was recovered from a hot spring (95oC) in Wyoming. The cells lack a nucleus, have a cell wall that lacks peptidoglycan, and have 70S ribosomes. Analysis of the plasma membrane reveals that the lipids contain long-chained branched hydrocarbons with ether linkages. Please choose the group in which this organism would be classified, based on the description provided. Protista

Answer 1

Archaea.

Step-by-step explanation:

The three domains of life are archaea, eubacteria and eukarya. The bacteria and archaea are prokaryotes whereas the eukarya is include in the eukaryotes according to the biological classification.

The archaea are found under the extreme environmental conditions. The nucleus and peptidoglycan layer is absent in archaea and they have 70S ribosomes. They have ether linkages in their plasma membrane structure. The new organism must belong to archaea as it shows all these characteristics.

Thus, the correct answer is archaea.

Answer 2

It is the Archaea. The Archaea constitute an area and kingdom of single-celled microorganisms. These microorganisms are prokaryotes, which means they have no cell core or some other layer bound organelles in their cells.
Archaea are microorganisms that characterize the breaking points of life on Earth. They were initially found and depicted in extraordinary conditions, for example, aqueous vents and earthly hot springs. They were additionally found in a different scope of profoundly saline, acidic, and anaerobic conditions.
