Question

Which option(s) correctly match(es) the structures in a bacterial cell (Column I) with their corresponding functions (Column II)?

• A. P - i; Q - ii; R - iii; S - iv
• B. P - i; Q - iii; R - ii; S - iv
• C. P - i; Q - iv; R - iii; S - ii
• D. P - ii; Q - iv; R - i; S - iii

Hint:

Each structure in a bacterial cell has specific functions that contribute to its survival and interaction with the environment. The cell wall, fimbriae, flagella, and pili all play critical roles in bacterial physiology and movement.

Answer 1

The Correct Option is A

Let's match each structure in the bacterial cell to its corresponding function:
- P. Cell wall: The cell wall provides structural support and protection from osmotic stress. Hence, P - i is correct.
- Q. Fimbriae: Fimbriae are short, hair-like structures that help the bacterial cell attach to surfaces. Hence, Q - ii is correct.
- R. Flagella: Flagella are long, whip-like appendages responsible for bacterial motility, enabling the cell to move. Hence, R - iii is correct.
- S. Pili: Pili are involved in the transfer of genetic material between bacterial cells during conjugation. Hence, S - iv is correct.
Thus, the correct answer is (A), where:
- P matches with i (Protection from osmotic stress),
- Q matches with ii (Attachment to surfaces),
- R matches with iii (Motility),
- S matches with iv (Transfer of genetic material).
