Current Question (ID: 11898)

Question:

$\text{The outermost limiting layer of mycoplasma is made up of}$

Options:

1. $\text{cell wall}$
2. $\text{cell membrane}$ (Correct)
3. $\text{mucilaginous sheath}$
4. $\text{slime layer}$

Solution:

$\text{Explanation:}$ $\text{Mycoplasma are the smallest and simplest free living Gram negative prokaryotes or monerans. A cell wall is absent. Plasma membrane forms the outer boundary of the cell. A substantial amount of polysaccharides having acetyl glucosamine are associated with cell membrane.}$ $\text{Key characteristics of Mycoplasma:}$ $\text{- They lack a rigid cell wall structure}$ $\text{- The plasma membrane serves as the outermost limiting layer}$ $\text{- The membrane contains polysaccharides with acetyl glucosamine}$ $\text{- They are the smallest free-living prokaryotes}$
