Question: In which group of organisms are mesosomes found?
Options:
Algae
Bacteria
Protozoa
Fungi
–
📌Other Options Explanations:
-(a) Algae: Algae are eukaryotic organisms. They have membrane-bound organelles, like chloroplasts.
-(c) Protozoa: Protozoa are also eukaryotic organisms. Instead, they have a complex internal structure with organelles like a nucleus and mitochondria.
-(d) Fungi: Fungal cells have mitochondria for energy production and cell walls different from bacterial membranes.
🔑Key Points:
-Mesosomes was discovered by F. James.Â
-Bacterial cell membrane that develops as an ingrowth from the plasma membrane.
-They increase the surface area of the plasma membraneÂ
-These are functionally mitochondria like structures.
-Mesosomes are present only in Aerobic bacteria.
-The mesosomes are of two types based on position and function.
-Peripheral mesosome- Situated near the cell membrane in the peripheral part and their main function is cell respiration and cell wall secretion. Which is analogous to mitochondria.
-Central mesosomes- Situated in the cytoplasm and their main function is providing help in DNA replication and cell division.
