Detailed explanation-1: -Mycoplasma is the smallest prokaryotic organism (0.15 to 0.35 micrometer) that lacks cell wall but have rigid plasma membrane rich in sterols and lipoglycans.

Detailed explanation-2: -Mycoplasmas are the smallest and simplest prokaryotes capable of self-replication, with information provided by a genome which may be as small as 600 kb, estimated to carry less than 500 genes.

Detailed explanation-3: -They are organisms which do not have proper cellular organization i.e they lack cellular organelles and a nucleus and therefore are small in size.

Detailed explanation-4: -Cell Size. At 0.1 to 5.0 m in diameter, prokaryotic cells are significantly smaller than eukaryotic cells, which have diameters ranging from 10 to 100 m ([link]). The small size of prokaryotes allows ions and organic molecules that enter them to quickly diffuse to other parts of the cell.

Detailed explanation-5: -Mycoplasma gallicepticum is the smallest cell. Mycoplasma’s size is 0.2–0.3 m. Mycoplasma are the smallest living organisms on the earth.
