What is a mesosome in a prokaryotic cell? Mention the functions that it performs.

(N/A) mesosome is a convoluted membranous structure formed in a prokaryotic cell by the invagination of the plasma membrane.
Its functions are as follows:
$1$. It aids in the synthesis of the cell wall and the replication of $DNA$.
$2$. It assists in the equal distribution of chromosomes into daughter cells.
$3$. It increases the surface area of the plasma membrane to facilitate various enzymatic activities.
$4$. It plays a role in secretion processes and bacterial respiration.
