Question

Match List I with List II 

Choose the correct answer from the options given below: 
 

• A. A-III, B-IV, C-II, D-V, E-I
• B. A-II, B-IV, C-III, D-V, E-I
• C. A-III, B-V, C-II, D-IV, E-I
• D. A-II, B-V, C-I, D-IV, E-III

Hint:

Hyperplasia = more cells (Tumor/Gall).
Hypertrophy = bigger cells (Bakanae elongation).
Necrosis = death (Scorched appearance).

Answer 1

The Correct Option is B

Step 1: Understanding the Question:
The question asks to match specific physiological or morphological plant responses (symptoms) with the diseases that characteristically cause them.

Step 2: Detailed Explanation:

• Chlorosis (A-II): Yellowing due to chlorophyll degradation. This is the hallmark of Tobacco Mosaic Virus (TMV), which creates "mosaic" patterns of green and yellow.

• Hyperplasia (B-IV): Abnormal increase in cell number. In Crown Gall (Agrobacterium), cell proliferation leads to large tumor-like growths.

• Epinasty (C-III): Downward bending of leaves often seen in Bacterial Wilt as an early response to vascular stress and hormonal changes (ethylene).

• Etiolation (D-V): Rapid, pale, spindly growth. Bakanae ("foolish seedling") disease is caused by gibberellins produced by Gibberella fujikuroi, causing extreme elongation.

• Necrosis (E-I): Death of tissue. Fire blight causes rapid blackening and death of flowers and shoots, looking like they were scorched by fire.
Final Answer:
The correct matching is A-II, B-IV, C-III, D-V, and E-I. This is found in option (B).
