Question

VAM (Vesicular-arbuscular mycorrhizae) represents

• A. Saprophytic bacteria
• B. Symbiotic fungi
• C. Saprophytic fungi
• D. Parasitic algae

Answer 1

The correct option is B Symbiotic fungi

Mycorrhiza biofertilizer is also known as VAM, adheres to plants rhizoids leading to development of hyphae. Hyphae boost development and spreading of white root in to soil leading to significant increase in rhizosphere. These hyphae further penetrate and form arbuscules within the root cortical. VAM fungi form a special symbiotic relationship with roots of plant that can enhance growth and survivability of colonized plants. Mycorrhiza biofertilizer is very useful in organic farming as well as normal commercial farming. So, VAM is a symbiotic fungi and not a parasitic algae, saprophytic bacteria and saprophytic fungi. Thus, the correct answer is option B.
