(A) Enhancing its phosphorus uptake capacity
(B) Increasing its tolerance to drought
(C) Enhancing its resistance to root pathogens
(D) Increasing its resistance to insects

A

Enhancing its phosphorus uptake capacity

B

Increasing its tolerance to drought

C

Enhancing its resistance to root pathogens

D

Increasing its resistance to insects

Text Solution

Verified by Experts

The correct Answer is:
D
Mycorrhiza (symbiotic association between root and fungi) help the host plant in enhancing its phosphorus uptake capacity, increasing its tolerance to drought and enhancing its resistance to root pathogens. e.g. Glomus.
