Do archaea have Pilus?

Accordingly, do archaea have endospores?

Endospores are capable of surviving radiation, drying, temperature extremes and disinfectants. They also allow bacteria to survive long periods in harsh environments. Archaea are well-known for their ability thrive in harsh environments that other organisms cannot tolerate.

Also, archaea may have ribosomes. The small ribosomal subunits of Archaea have some structural features ('bills' and 'lobes) that are also found in Eukarya. The Archaeal subunits of ribosomes consist of 30S and 50S units that combine to form a 70S particle. They are composed of 3 rRNA molecules (16S-23S and 5S), and as many as 68 ribosomal protein.

So, does archaea also have capsules?

Plasmids are extra-chromosomal DNA that is found in many species. These are the characteristics of a typical protozoan cell. All prokaryotes lack flagella, capsules, or pili.

Are archaea able to produce plasmids from plasmids in their environment?

Archaeans are similar to bacteria in that they have no internal membranes. Their DNA is stored as a single loop, called a plasmid. Their tRNAs are unique in that they have many features that are not found in other living organisms. The tRNA molecules, which are short for "transferRNA", are crucial in decoding DNA's message and building proteins.
