Question

Match the correct mode of cell division with respective bacteria.

• A. (P)-(ii), (Q)-(iii), (R)-(i), (S)-(iv)
• B. (P)-(ii), (Q)-(i), (R)-(iii), (S)-(iv)
• C. (P)-(iv), (Q)-(ii), (R)-(i), (S)-(iii)
• D. (P)-(i), (Q)-(iv), (R)-(iii), (S)-(ii)

Hint:

In bacterial cell division, binary fission is the most common form, but some species like Streptomyces exhibit unique forms such as fragmentation.

Answer 1

The Correct Option is C

Step 1: Understanding the question.
This question asks to match the correct mode of cell division (represented by different shapes) with the bacteria listed.
Step 2: Analyzing the options.
- (P) Streptomyces species: These bacteria typically exhibit a unique mode of cell division that is represented by option (iv), where they undergo septal formation and fragmentation.
- (Q) Rhodopseudomonas acidophila: This bacterium divides via binary fission, and the mode of division corresponds to (ii), which shows a simple separation of a single cell into two.
- (R) Bacillus subtilis: This bacterium divides by binary fission, represented by (i), showing simple elongation and division.
- (S) Nocardia species: These bacteria divide in a manner where new cells are formed with external growth, represented by (iii).
Step 3: Conclusion.
Thus, the correct matching is (P)-(iv), (Q)-(ii), (R)-(i), (S)-(iii), which corresponds to option (C).
