Q. Mycorrhiza, a mutal relationship between fungus and a root of gymnosperm helps in I. absorption of water II. mineral absorption III. translocation IV. gaseous exchange Choose the correct option
A) Only I
B) II and I
C) III and IV
D) Only II
Explanation
Mycorrhiza is a mutual association between fungus and roots of gymnosperms, like Pinus. In this relationship the fungal hyphae extends into the soil and absorb water and minerals from the soil. This absorbed minerals and water is handed over to the roots of the plants, which in turn provides sugar and N-compound to the fungal hyphae
