15. Which of the following microbes fail to form cell wall under environmental factors? 1-Mycobacterium sp 2-Mycoplasma sp 3-Candida sp 4-L-forms

The correct answer is 2-Mycoplasma sp.Mycoplasma species are unique among bacteria in that they lack a cell wall. This characteristic allows them to be highly adaptable to changing environmental conditions. Unlike other bacteria that rely on a rigid cell wall for structural support and protection, Mycoplasma species have a flexible cell membrane that can change shape and size. This flexibility enables them to invade host cells and evade the immune system, making them opportunistic pathogens.
