Question

Which of the following statement about Mycoplasma is true?

• A. They are smallest, disease causing thin walled organisms.
• B. They differ from viruses in being cellular organization.
• C. Insensitive to several antibiotics as they have 70S ribosomes.
• D. They can survive without photosynthetic pigments and genetic material.

Answer 1

The correct option is A They are smallest, disease causing thin walled organisms.

Mycoplasma are the smallest bacterial cells yet discovered. They lack a cell wall around their cell membranes. This characteristic makes them naturally resistant to many antibiotics such as penicillin and other beta-lactam antibiotics that target cell wall synthesis. They are pathogenic in humans, including Mycobacterial pneumoniae. They can survive without oxygen.

So, the correct answer is 'They are smallest, disease-causing thin walled organisms'.
