QUESTION: Mesosomes are the part of

ANS:

  • Mesosomes were initially described as invaginations of the plasma membrane in certain bacteria such as Gram-positive species.
  • They were believed to extend into the cytoplasm, forming compartments that were connected to the plasma membrane.
  • Some researchers argue that the observed mesosomes could be the result of the shrinkage and folding of the plasma membrane during the fixation and dehydration processes involved in sample preparation for electron microscopy.

 

Aspect                 Detail
Structure·        Mesosomes are membrane invaginations observed in certain bacterial cells.
Function·        Proposed functions include involvement in cell division, DNA replication, and energy metabolism.
Location·        In Gram-positive bacteria mesosome observed at the poles but distribution can vary among species.
·        In Gram-negative bacteria mesosome like structures can occur at the poles, lateral sides, or around the nucleoid.
