A. absorption of water
B. mineral nutrition
C. translocation
D. gaseous exchange.

• A. Only A
• B. Only B
• C. Both A and B
• D. Both B and C

Answer 1

The correct option is C Both A and B

The roots of some higher plants are associated with fungal mycelia. Such an association is called mycorrhiza. It represents a mutualistic(symbiotic) association between the root system of higher plants and fundal hyphae. The fungal hyphae form a network around the young root and invade the root cells. The external hyphae greatly increase the surface area for absorption of minerals and water from a much larger volume of soil that perhaps the roots alone cannot do.

So, the correct answer is 'Both A and B'.
