What is bacterial mesosome?

Answer 1

In some locations, the cell membrane forms internal folds in the cytoplasm called mesosomes.

Denying all claims of having functional role, recent studies have shown that mesosomes are artifacts of preparation, resulting from stain fixation.

Answer 2

A mesosome is the term used for a folded-in place found on the side of a bacteria that has been prepared as a slide. This structure appears when bacterial cells have been fixed to a slide by chemical means. It is not seen when the same types of cells are frozen instead.

Answer 3

mesosomes are the infoldings in the plasma membrane,these are rich in enzymes that helps to perform functions like cellular respiration,DNA replication,secretion of glycocalyx and cell division(most imporatant function;it increases the surface area of the cell membrane

Answer 4

these are vesicular lamellar or tubular pockets formed by the invagination of the cell membrane . These structure are more prevalent in gram +ve bacteria .Due to presence of respiratory enzymes and in the absence of mitochondria , mesosomes are said to be respiratory in function .

Answer 5

A bacterial mesosome is a structure found in some bacterial cells that is involved in cell division. It plays a role in separating newly replicated DNA molecules during cell division. Some studies suggest that its function might also include roles in respiration and DNA replication.

Answer 6

No function. These are just invaginations that are caused by preparing bacteria for electron microscopy.
