Q. In mycorrhizal association, which one of the following increases the surface area available for absorption of water and minerals by roots?
A) Mycorrhiza
B) Numerous branches of root
C) Root hairs
D) None of the above
Explanation
In mycorrhizal association, a large number of fungal hyphae are associated with the roots of higher plants in which hyphae extend to sufficient distance into soil and have a large surface area. These hyphae absorb water and mineral from the soil and pass them to roots. Roots provide sugar and nitrogen compound to the fungal hyphae
