Question

Select a wrong statement.

Easy

A

Bacteria cell wall is made up of peptidoglycan.
B

Pilli and fimbriae are mainly involved in motility of bacterial cells.
C

Cyanobacteria lack flagellated cells.
D

Mycoplasma is a wall – less microorganism.

Solution

Bacteria cell wall is made up of peptidoglycan.
Pilli and fimbriae are not involved in motility of bacterial cells. Rather pilli helps in attachment of one bacterial cell to another. The fimbrae helps in attachment of the bacteria to the substratum.
They lack flagella and hence they are non-motile.
Mycoplasma do not possess a cell wall. This makes the cell pleomorphic in nature.
