Solution
The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Mycorrhizae refer to the symbiotic association of fungal hyphae with the
roots of higher plants. In this association, the two symbiotic are in
close contact and are physiologically interdependent on each other.
Mycorrhizae increase the ability of the plant to extract minerals from the
soil. In return,fungi are provided with shelter and products of
photosynthesis by the plant. Plants having such associations shows other
benefits also, such as resistance to rot-Borneo pathogens, tolerance
too salinity and drought and an overall increase in plant growth and
development.
So, the correct answer is 'Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion'.
