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
Increasing its resistance to insects
Explanation
Solution
Fungi are also known to form symbiotic associations with plants (mycorrhiza). Many members of the genus Glomus form mycorrhiza. The fungal symbionts in these associations absorb phosphorus from soil and pass it to the plant. Plants having such associations 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.
