Question

In a prokaryotic cell, mesosomes functions is

• A. DNA replication and distribution to daughter cells.
• B. Formation of cell wall, increase the surface area of
  
  the plasma membrane and enzymatic content.
• C. Respiration and secretion processes.
• D. All of these

Answer 1

Answer: (D)

A special membranous structure is a mesosome that is formed by the extensions of the plasma membrane into the cell. These extensions are in the form of vesicles, tubules, and lamellae. They help in cell wall formation, DNA replication, and distribution to daughter cells. They also help in respiration, secretion processes, to increase the surface area of the plasma membrane and enzymatic content.
