Mycorrhiza does nto help the host plant in

Options

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

Answer

D

Explanation

Fungi form symbiotic association with the roots of higher plants called mycorrhiza (VAM) e.g. Glomus. The fungai hyphae symbiont in these associations absorb phosphorus from soil and passes it to the plant. Plants having such associations show other benefits also, such as resistance to root-borne pathogensm tolerance to salinity and draught, and an overall increase in plant growth and development. Mycorrhiza does not help the host plant in increasing its resistance to insects.
