Question

Given below are two statements, one is labelled as Assertion (A) and other labelled as Reason (R).
Assertion (A): Active dissemination and infection is observed in flagellated plant pathogens like Phytophthora
Reason (R): Root exudates attract zoospores of Phytophthora
In light of the above statements, choose the correct answer from the options given below:

• A. Both (A) and (R) are true and (R) is the correct explanation of (A).
• B. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
• C. (A) is true but (R) is false.
• D. (A) is false but (R) is true.

Hint:

Flagellated zoospores of oomycetes like Phytophthora use chemotaxis to swim actively toward host root exudates, which facilitates targeted infection.

Answer 1

The Correct Option is A
