Question

A specialised membranous structure in a prokaryotic cell which helps in cell wall formation, DNA replication and respiration is ______.

Options

• Mesosome

• Chromatophores

• Cristae reticulum

• Endoplasmic

Answer 1

A specialised membranous structure in a prokaryotic cell which helps in cell wall formation, DNA replication and respiration is mesosome.

Explanation:

In prokaryotic organisms, particularly bacteria, mesosomes are infoldings of the plasma membrane. They are linked to several processes, including respiration, DNA replication, and cell wall formation. The surface area available for enzyme activity is increased by these structures. In eukaryotic cells, they are not present.
