Question

Can prokaryotes be multicellular?

Answer 1

Prokaryotic cells are present in unicellular species. They're known as prokaryotes. The prokaryotic cell contains a number of components that enable it to act as a living organism.

Complete answer:
Bacterial cells vary significantly from those of multicellular species such as humans. As a result, bacteria are almost entirely single-celled organisms with their own autonomy and mobility. Many bacteria, such as biofilms and colonies, form large interconnected structures.

Biofilms normally form on surfaces and bind to them. Some of the most well-studied biofilms are made up of prokaryotes, while fungal biofilms and biofilms made up of fungi and bacteria have also been identified.

Multicellular prokaryotes DO exist. Biofilms are what they're called. Microbes secrete a polymeric slime that acts as an adhesive, allowing them to adhere to either an animate or inanimate material, forming biofilms. More cells arrive and bind to the same secretion, and the multicellular unit grows from there by more polysaccharide secretions, cell recruitment, and cell division.

Internally, the multicellular unit interacts and collaborates as a unit. Some of the group's cells, for example, secrete sticky polymers to cling to an intestinal wall, whereas others collect nutrients from the bloodstream as well as other biological building blocks including fibrils for increased communication.

A multicellular unit is formed when two or more cells bind to one another and collaborate for a shared goal. After all, they work as a team, perform distinct activities, and gradually become virtually inseparable. In a process known as "quorum sensing," they interact with one another and seem to think as a group.

No, there is no such proof that multicellular prokaryotes exist. It appeared to indicate the existence of multicellular bacteria, according to some studies and evidence, but this was not confirmed.

Note: All of these requirements for multicellularity, such as mitochondria and a nucleus that can contain or compartmentalize fine-tuning introns in a larger genome, as well as the numerous proteins needed for multicellular organism survival, are absent in a prokaryotic cell. It's also difficult to integrate them into a prokaryotic cell due to their small size and lack of membrane bound nucleus and other organelles.As a result, a multicellular prokaryote is not possible.
