Answer:

C) Most likely an archaeon

Explanation:

Because this new microorganism has a rigid cell wall but lacks of peptidoglycan it is very likely that this is not a bacterium; bacterial cell walls are made of peptidoglycan.  

This new microorganism cannot be an eukaryote either because all eukaryotes have a nucleus in their cells.

It is possible that the new microorganism is an archeon (belongs to the Archea domain) because organisms within Archea have cell walls assembled from surface-layer proteins. Also, Archaea and bacteria are generally similar in size and shape including  2 μm microorganism and coccoid shapes.

Which characteristics do cell membranes and cell walls have in common?
earnstyle [38]
<span>Both protexts the organisms' organelles which are inside the cell.
Animal Cell: Cell Membrane
Plant Cell: Cell Wall
Cell wall is present only in plants, it is not found in all organisms. Compared to the cell membrane, a cell wall is thick and has a rigid structure. You can see it in a light microscope, because it is visible. It serves as the protective cover that surrounds the plasma membrane in a plant cell. Cell membrane is composed of lipids. Cell walls can be made up of cellulose or peptidoglycan or chitin.<span> </span></span>
