Mycorrhiza does not help the host plant ...

Mycorrhiza does not help the host plant in: 1. enhancing its phosphorus uptake capacity 2. increasing its tolerance to drought 3. enhancing its resistance to root pathogens 4. 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

Fungi are also known to form symbiotic associations with plants (mycorrhiza). Many members of the genus Glomus form mycorrhiza. The fungal symbionts in these assocaitions absorb phosphorus from soil and pass it to the plant. Plants having such association show other benefits also, such as resistance to root-borne pathogens, tolerance to salinity and drought, and an overall increase in plant growth and development.
