Detailed explanation-1: -A specialized membraneous structure is a mesosome which is formed by an extension of plasma membrane into the cell. These extensions are in the form of vesicle, tubules, and lamellae . They help in Cell wall formation, DNA replication and distribution to daughter cells.

Detailed explanation-2: -EXPLANATION: A special membranous structure is formed by the extensions of plasma membrane into the cell. This is called the mesosome. These extensions are in the form of vesicles, tubules and lamellae.

Detailed explanation-3: -Mesosomes are organelles formed by plasma membrane infoldings. They are found in the membranes of bacterial cells. They’re invaginated structures made up of vesicles and tubules with lamellar whorls. Flat vesicles form the lamellae, which are connected to the cell membrane.

Detailed explanation-4: -Mesosome is the extension of plasma membrane into the cytoplasm. It helps in cell wall formation, DNA replication, respiration secretion process, increases the surface area of plasma membrane and enzymatic contents. It also helps in cytokinesis.

Detailed explanation-5: -So, the correct answer is, ‘Mesosomes. ‘-Mesosome: It is formed by the extension of the plasma membrane into the cell wall. This forms some uneven folded shapes, such as vesicles, tubules, and lamellae.
