Mesosomes are membranous invaginations found in certain bacteria, especially Gram-positive ones. They are thought to play a role in respiration, cell division, and DNA segregation. There is some debate among scientists about their exact function.
Just invaginations in gram positive bacteria due to chemical fixing. Now just considered artifacts of said fixing.

Do Eukeryotic cells have mesosomes?
No, mesosomes are not present in eukaryotic cells. Mesosomes are structures found in bacterial cells and are believed to play a role in cell division and respiration. Eukaryotic cells do not have the same type of membrane-bound organelles as bacteria.
What is the difference between cristae and mesosome?
Cristae are internal folds of the inner mitochondrial membrane that increase surface area for cellular respiration. Mesosomes are invaginations of the plasma membrane in prokaryotic cells that are involved in cellular processes like cell division and respiration. Mesosomes are not found in eukaryotic cells.
What is the difference between mesosome and episomes?
Mesosomes are infoldings of the plasma membrane in bacterial cells that participate in cell division, DNA replication, and cell wall synthesis. Episomes, on the other hand, are extrachromosomal genetic elements that can exist either autonomously as plasmids or integrate into the host cell genome. Episomes can replicate independently or be passed on to daughter cells during cell division.
If a function is equal to zero when x is zero is the function considered defined at that point?
Yes, if the function is equal to zero at x=0, the function is considered defined at that point. The function's value at x=0 does not impact its overall definition.
When the anatomy of a body part is intimately tied to its specific function scientists call this the principle of?
principle of complementarity of structure and function
Do Eukeryotic cells have mesosomes?
No, mesosomes are not present in eukaryotic cells. Mesosomes are structures found in bacterial cells and are believed to play a role in cell division and respiration. Eukaryotic cells do not have the same type of membrane-bound organelles as bacteria.
Does plant cell have Mesosome?
No, mesosomes are structures found in prokaryotic cells, not in plant cells. Mesosomes are used for cellular respiration and are involved in cell division in prokaryotic organisms. Plant cells do not have mesosomes because they are eukaryotic and have a different structure and organization.
What are the irregular in-folding of the plasma membrane of bacterial cells?
Irregular in-foldings of the plasma membrane in bacterial cells are known as mesosomes. These structures are believed to be involved in cell division and DNA replication, but their exact function is still debated among researchers. Mesosomes may also play a role in organizing enzymes for metabolic pathways within the cell.
What is the structure and the function of the mesosome?
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.

What is the difference between cristae and mesosome?
Cristae are internal folds of the inner mitochondrial membrane that increase surface area for cellular respiration. Mesosomes are invaginations of the plasma membrane in prokaryotic cells that are involved in cellular processes like cell division and respiration. Mesosomes are not found in eukaryotic cells.
Does archaea have mitocondria?
No, archaea do not have mitochondria. They have unique membrane-bound structures called "mesosomes" that serve a similar function to some extent. Archaea are prokaryotic organisms and do not possess complex organelles like mitochondria found in eukaryotic cells.
What is bacterial mesosome?
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.
Why bacterial mesosome similar to mitochondrial crestae?
Bacterial mesosomes and mitochondrial cristae are both internal membrane structures that increase surface area for cellular processes. Mesosomes in bacteria are involved in cell division and DNA replication while cristae in mitochondria are involved in cellular respiration. Both structures help maximize the efficiency of cellular functions by providing more surface area for reactions to occur.
Do only animals have mitochondria?
No. Other cells such as plant cells contain mitochondria. However, prokaryotic cells such as bacteria do not contain mitochondria and respiration instead occurs on infolds in the plasma membrane called mesosomes.
What do eukaryotes lack?
Eukaryotes lack a cell wall made of peptidoglycan, which is present in prokaryotic cells. Additionally, some eukaryotes lack flagella or cilia for motility, which are common in prokaryotic cells.
How is the prokaryotic bacterium in the different from a eukaryotic cell?
Prokaryotic cells do not have nucleus They have ribosomes of 70s type All cell organelles are absent They have mesosomes meant for respiration Eukaryotes have well defined nucleus They have ribosomes of 80s type All cell organelles are presesnt They have mitochondria to perform respiration
Does procariots have mitochondria?
No, prokaryotes do not have mitochondria. Mitochondria are membrane-bound organelles found in eukaryotic cells, which are more complex than prokaryotic cells. Prokaryotes generate energy through other means, such as through the plasma membrane or specialized membrane structures called mesosomes.
