Vesicular- arbuscular mycorrhiza (VAM) is a symbiotic association between certain fungi and angiosperm roots. - VAM is endomicorrhizal association, lives in cortex of root, mostly in intercellular spaces with some hyphal tips passing inside cortical cells. It has significant role in phosphate nutrition of plants.

Nostoc does not form symbiotic association with
1 Cycas
2 Anthoceros
3 Pinus
4 Gunnera
Explanation:
Nostoc species form symbiotic associations with bryophytes (Anthoceros), the pteridophyte fern Azolla, gymnosperm cycads and the angiosperm genus Gunnera. It does not form symbiotic association with Pinus. - Pinus forms symbiotic association with fungal hyphae is called mycorrhiza. In this association both the organisms get mutually benefitted.

Among the following pairs of microbes, which pair has both the microbes that can be used as biofertilizers?
1 Aspergillus and Cyanobacteria
2 Aspergillus and Rhizopus
3 Rhizobium and Rhizopus
4 Cyanobacteria and Rhizobium
Explanation:
Biofertilizers are the suspension of microorganism which mainly increases the growth of the plants. These secrete the growth promoting substances. Both cyanobacteria and Rhizobium are used as bio fertilizers. Cyanobacteria (BGA) are able to fix atmospheric nitrogen. They can convert nitrogen from the air into a form that plant can use. Rhizobium is able to fix nitrogen fixation and the symbiotic relationship with leguminous plants.

Consider the following statements (A-D) about organic farming
1 (A) and (B) only
2 (B), (C) and (D
3 (C) and (D) only
4 (B) and (C) only
Explanation:
Organic forming means not use any types of inorganic fertilizer, pesticides, insecticides. - Pure used organic wasted like as cow dunk, bacteria, algae \& fungi etc. - Organic farming used to increase agriculture productivity and maintain sustainable soil productivity, but not to produce particularly, vegetable rich in vitamins and minerals.
