1.	Question : Assertion : Mycorrhizae represent a mutually beneficial interspecific interaction of fungi with roots of higher plants. Reason : In a mutualistic relationship, both the organisms enter into some sort of physiological exchange.
Answer» Solution :Mycorrhizae refer to the symboitic association of fungal hyphae with the roots of higher plants. In this association, the two symbionts are in close contact and are physiologically interdependent on each other. Mycorrhizae increase the ability of the plant to EXTRACT minerals from the SOIL. In return, fungi are provided with shelter and products of photosynthesis by 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.
