Incorrect statement about Mycoplasma:
It has rigid cell wall.
Explanation:
Mycoplasma is a unique type of bacteria that lacks a rigid cell wall. Instead, it has a flexible cell membrane that allows it to take on different shapes and sizes. This lack of a cell wall also makes Mycoplasma resistant to certain antibiotics that target cell wall synthesis. Some other characteristics of Mycoplasma include:
- It adopts a parasitic mode of nutrition, meaning it requires a host organism to survive and reproduce.
- It is present in various locations in the human body, including the urogenital tract and blood smears.
- Mycoplasma is one of the smallest living cells, but it is not the smallest. Some viruses and bacteria are smaller.
