Correct answer
Explanation
Bacteria that are naturally having no cell walls include Mycoplasma and Ureaplasma. Ureaplasma is a type of bacteria in the family of bacteria known as Mycoplasma. These bacteria are incredibly tiny and are unique in that they lack a cell wall. Because the cell wall is the part of the bacteria attacked by a number of antibiotics, some common antibiotics such as those in the beta lactam family are not effective against these bacteria.
