The organism that completely lack a cell wall and are smallest living ...
Mycoplasmas are the smallest living cells that lack a cell wall and can survive without oxygen. Let's understand this in detail:
Explanation:
- Mycoplasmas are a type of bacteria that belong to the class Mollicutes.
- Unlike other bacteria, mycoplasmas lack a cell wall, which makes them unique.
- The cell wall provides rigidity and shape to bacterial cells, but since mycoplasmas lack this structure, they have a flexible cell membrane that allows them to change shape and move easily.
- Mycoplasmas are very small, with a diameter of about 0.1-0.2 micrometers, which makes them the smallest known cells that can replicate independently.
- Mycoplasmas can survive in a variety of environments, including those that are low in oxygen, or even oxygen-free.
- They are found in a wide range of hosts, including humans, animals, and plants, where they can cause infections and diseases.
Importance:
- Mycoplasmas are important research organisms because they are simple, easy to grow in the laboratory, and can be used as models to study basic biological processes.
- They are also used in biotechnology and medicine, for example, mycoplasmas can be engineered to produce proteins or vaccines.
- Mycoplasmas are also important pathogens, causing diseases such as pneumonia, urinary tract infections, and genital infections.
Conclusion:
Mycoplasmas are the smallest living cells that lack a cell wall and can survive without oxygen. They are important research organisms and can cause diseases in humans and animals.
