Mycorrhiza does not help the host plant in:

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

Answers (1)

The answer is option (d) Increasing its resistance to insects.

Explanation: Mycorrhiza does not enhance a plant's resistance to insects. It primarily supports the plant by improving phosphorus absorption, drought tolerance, and protection against root pathogens through its fungal hyphae. The symbiotic relationship between fungi and plant roots boosts nutrient uptake, especially in nutrient-poor soils, and enhances water absorption, aiding in drought resilience. However, mycorrhiza does not provide a direct defense against insect pests.
