Mesosome in a cell is a :
- Membrane bound vesicular structure
- Chain of many ribosomes attached to a single mRNA
- Special structure formed by extension of plasma membrane
- Medium sized chromosome
Answer
(3) Special structure formed by extension of plasma membrane

In prokaryotes, the mesosome is a special membranous structure formed by the extension (infolding) of the plasma membrane into the cell, as vesicles, tubules and lamellae.
It helps in cell wall formation, DNA replication and distribution to daughter cells, respiration and secretion.
