Question

Given below are two statements:
Statement I: Spatial and temporal transmission of plant pathogens are in general guided by asexual and sexual spores.
Statement II: Bacterial pathogens produce asexual cells.
In the light of the above statements, choose the most appropriate answer from the options given below:

• A. Both Statement I and Statement II are true
• B. Both Statement I and Statement II are false
• C. Statement I is correct but Statement II is false
• D. Statement I is incorrect but Statement II is true

Hint:

Pathogen transmission:
- Asexual spores: Rapid spread (spatial transmission).
- Sexual spores: Survival, genetic variation.
- Bacteria: Reproduce asexually by binary fission.

Answer 1

The Correct Option is D

Step 1: Understanding the Question:
This question tests knowledge of pathogen transmission and reproduction.

Step 2: Detailed Explanation:
Statement I:
Spatial and temporal transmission of plant pathogens are guided by asexual spores.
Sexual spores are involved in survival and genetic variation, not primarily in spatial transmission.
Asexual spores are responsible for rapid spread and multiple infection cycles.
This statement is false.
Statement II:
Bacterial pathogens produce asexual cells.
Bacteria reproduce asexually by binary fission.
They do not produce sexual spores.
This statement is true.

Step 3: Final Answer:
Thus, Statement I is incorrect but Statement II is true, which corresponds to option (D).
