Mycoplasmas differ from other bacteria in that they?
lack a cell wall, making them resistant to certain antibiotics that target this structure in bacteria. They are among the smallest known free-living organisms and have a streamlined genome. Mycoplasmas are also known for their ability to colonize various host tissues due to their small size and flexible shape.
What if the plant cell don't have cell wall?
Without a cell wall a plant cell will not be stable, because a cell wall provides a cell with structural support and protection. A cell wall acts as a pressure vessel, preventing over-expansion when water enters the cell.
Cells without cell wall is called as?
Cells without a cell wall are typically found in animals and are called animal cells. These cells rely on other structures like the plasma membrane for support and protection, instead of a rigid cell wall.
What phylum does a bacterium belong to if it doesn't have a cell wall?
Bacteria without a cell wall would belong to the phylum Tenericutes. Tenericutes are a group of bacteria that have a unique cell membrane but lack a cell wall.
Why animal cells are able to survive without cell walls?
Animal cells are able to survive without cell walls because they have a flexible cell membrane that provides structure and protection. The absence of a rigid cell wall allows animal cells to change shape and move, which is important for many cellular functions. Additionally, animal cells rely on the supportive structure provided by the extracellular matrix and other cytoskeletal components to maintain their shape and integrity.
Why are Mycoplasmas pleomorphic?
Mycoplasmas lack a cell wall, which contributes to their pleomorphic nature. Without a rigid cell wall, they can change shape and size in order to adapt to different environmental conditions. This flexibility enables mycoplasmas to survive in a variety of host tissues and evade the host immune system.
What are mycoplasmas?
Mycoplasmas are a type of bacteria that lack a cell wall, making them unique from other bacteria. They are known for their small size and ability to cause infections in humans, animals, and plants. Mycoplasmas are often difficult to target with antibiotics due to their lack of a cell wall.
Which is the smallest organisms that lack cell wall and it is smallest living cell which can survive without oxygen?
Which is the smallest living cell which lacks cell wall and can survive without oxygen
Would penicillin be very effective against Mycoplasma?
No- because penicillin inhibits cell wall synthesis and Mycoplasmas don't have a cell wall.
Are prokaryotic cells surrounded by a cell wall?
No. Some bacteria, like mycoplasmas, lack cell walls.
Why are mycoplasmas resistant to antibiotics that interfere with cell wall synthesis?
Mycoplasma is a genus of bacteria which lack a cell wall.[1] Without a cell wall, they are unaffected by many common antibiotics such as penicillin or other beta-lactam antibiotics that target cell wall synthesis. They can be parasitic or saprotrophic. Several species are pathogenic in humans, including M. pneumoniae, which is an important cause of atypical pneumonia and other respiratory disorders, and M. genitalium, which is believed to be involved in pelvic inflammatory diseases.

Mycoplasmas are also known for their ability to colonize various host tissues due to their small size and flexible shape.
What are the only monerans that lack cell walls?
The only monerans that lack cell walls are mycoplasmas. However, most animals like the Protista do not have a cell wall either.
Why are drugs that target cell wall synthesis useful?
Without the cell wall, the bacteria will be susceptible to destruction by chemicals outside the plasma membrane (which is just inside the cell wall of bacteria), and it will not be able to survive.
Which bacteria do not have cell wall?
Mycoplasma and Thermoplasma are two examples of bacteria that lack a cell wall. These bacteria have evolved to survive without a rigid cell wall by utilizing alternative mechanisms for structural support and protection.
What is the difference between mycoplasmas and mycobacterium?
Mycobacteria are quite distinct from mycoplasma in a number of important ways. For example:Mycoplasma refers to a genus of bacteria that lacks a cell wall.Mycobacteria are acid-fast Gram-positive bacteria that have a very thick, protective, waxy cell wall.There are many other differences too. Here's how these organisms are classified:MycoplasmaOrder: MycoplasmatalesFamily: MycoplasmataceaeGenus: MycoplasmaMycobacteriaOrder: ActinomycetalesFamily: MycobacteriaceaeGenus: Mycobacterium
If animal cell has a cell wall?
Animal cells do not have cell walls. If they did - they animal would not be likely to survive, as the rigidity of the cell wall would restrict movement.
