Question

Consider the features given below:

(i) Lack of cell wall
(ii) Lack of ATP generating system
(iii) Are facultative anaerobes
(iv) Are resistive to Penicillin

(v) Contain muramic acid in cell wall

Choose the correct option w.r.t the smallest free-living monerans.

• A. All correct
• B. (ii) and (iii) are correct
• C. (ii), (iv) and (v) are incorrect
• D. (i), (iii) and (iv) are correct

Answer 1

The correct option is D (i), (iii) and (iv) are correct

The smallest free-living monerans are the Mycoplasma. The Mycoplasma are organisms that completely lack a cell wall. They are the smallest living cells known and can survive without oxygen. They are naturally resistant to many common antibiotics such as penicillin or other beta-lactam antibiotics that target cell wall synthesis.

So, the correct option is '(i) (ii) and (iv) are correct'
