Question

If bacteria can act as multicellular organisms, why are they classified as prokaryotes?

Answer 1

Prokaryotes are single-celled creatures that lack cellular compartmentalization, meaning that all of the organism's molecules are contained within the cell membrane. Eukaryotes are organisms with specialised compartments in their cells (called cell organelles) that perform specific functions. Mitochondria, for example, are important for the creation of energy in Eukaryotic cells. Other cell organelles are similarly specialised in distinct ways.

Complete answer:
Prokaryotes are organisms that lack cellular compartmentalization. Eukaryotes do not have to be multicellular to be eukaryotes.

Because bacteria lack any cellular compartments, they are classified as prokaryotes, despite the fact that they perform the same duties as multicellular creatures.

Cells are the most basic units that make up all lifeforms in existence. There are two major types of cells: eukaryotic and prokaryotic. Eukaryotic cells are complex and have a membrane-bound nucleus as well as many organelles that work to keep the cell functioning. Prokaryotes are much more simple, lacking a membrane-bound nucleus and most of the organelles found in eukaryotic cells.

Yes, prokaryotes are all single-celled organisms. However, many eukaryotes are single-celled organisms as well.

Bacterial cells differ significantly from those of multicellular creatures such as humans. They're a lot smaller, have a lot less internal organisation, and don't have a nucleus (they have DNA but it is not packaged safely within a membrane). Bacteria are nearly exclusively single-celled organisms having their own autonomy and mobility as a result of this.

Note:-
Kingdom Protista is a single-celled eukaryote that reproduces through fission. The presence of 70S bacteria and asexual reproduction by binary fission in protists suggest that they evolved from prokaryotic monerans, while cellular structure implies that multicellular eukaryotes evolved from protista. Protists are thus related to both prokaryotes and multicellular eukaryotes.
