Mesosomes are the infoldings of cell membrane, which(i) are present in...
The correct option is B (ii) and (iii)
Mesosomes are the areas in the cell membrane of prokaryotic cell which fold inwards. It helps in cell wall formation, DNA replication, respiration and increases the surface area of the plasma membrane.

Mesosomes:
Mesosomes are structures found in prokaryotic cells that are formed by inward folding of the cell membrane. They are not present in eukaryotic cells. Mesosomes play various important roles in the cell, including cell wall formation, DNA replication, and respiration.
Presence in Prokaryotic and Eukaryotic Cells:
Mesosomes are only present in prokaryotic cells, not in eukaryotic cells. Prokaryotic cells are simpler and lack membrane-bound organelles, including the nucleus. On the other hand, eukaryotic cells have a distinct nucleus and membrane-bound organelles. Therefore, option (i) is incorrect.
Functions of Mesosomes:
Mesosomes are involved in several important cellular processes. These functions include:
1. Cell Wall Formation: Mesosomes help in the synthesis and formation of the cell wall in prokaryotic cells. They play a role in the deposition of peptidoglycan, a major component of bacterial cell walls.
2. DNA Replication: Mesosomes are also involved in DNA replication. They help in the attachment and segregation of newly synthesized DNA molecules during cell division.
3. Respiration: Mesosomes are associated with respiratory enzymes and play a role in cellular respiration. They provide a large surface area for the attachment of these enzymes, which are involved in energy production.
Increase in Surface Area:
One of the key functions of mesosomes is to increase the surface area of the plasma membrane. The inward folding of the cell membrane creates numerous invaginations or infoldings, which result in the formation of mesosomes. These mesosomes provide a larger surface area for various cellular processes, such as nutrient uptake, enzyme attachment, and energy production.
Correct Answer Explanation:
Based on the information provided, option (b) is the correct answer. Mesosomes are not present in eukaryotic cells, so option (i) is incorrect. Mesosomes are involved in cell wall formation, DNA replication, and respiration, which aligns with option (ii). Additionally, mesosomes increase the surface area of the plasma membrane, supporting option (iii). Therefore, the correct answer is option (b) - (ii) and (iii).
