Mesosomes are cell organelles and are typically present in prokaryotes. They are analogous to the mitochondria in eukaryotes. Mesosomes are a part of the structure of the cell membrane, found on the inner side. Some of the key functions of mesosomes include increasing the surface area of the plasma membrane and aiding electron transport, photosynthesis, cell wall formation, and the like.

Mesosomes help with cell division, aiding cell wall synthesis and DNA replication. Another function they serve is the uniform distribution of chromosomes into the daughter cells from the parent cell. During cell division, a cross wall forms. Mesosomes begin the formation of this cross wall, or septum, and attach the bacterial DNA to the cell membrane. This results in the separation of the bacterial DNA into each of the resulting daughter cells.

Among the two types of the mesosomes (septal and lateral), the septal mesosomes participate in the cross wall formation. The bacterial chromosome is also attached to the septal mesosomes.
