notes on : fermicutes because they include the simplest classified as life form on earth: the Mycoplasma. it barely fits in this domain. it has no cell wall. it does have membrane though.
“The DNA of M. genitalium has been completely sequenced by microbiologists, who believe that it may be close to the theoretical lowest limit for a living functioning organism. The cell membranes of Mycoplasma species contain chemicals such as sterols and sometimes lipoglycans, which help them remain stable and resistant to osmotic lysis.”
