2 photosynthesis and nitrogen fixation simultaneously
3 only nitrogen fixation
4 either photosynthesis or nitrogen fixatior a time
Explanation:
Nostoc is photosynthetic blue green algae. It contains chlorophyll pigment and performs photosynthesis. It also has ability to fix atmospheric nitrogen, make it available to plants in a form they can use.

Micorrhiza is a
1 parasitic relation between fungus and algae
2 symbiotic relation between fungus and algae
3 symbiotic relation between fungus and roots
4 parasitic relation between fungus and roots
Explanation:
Micorrhiza is the symbiotic relationship between fungus and roots of higher plants. It is mutualistic relationship because both organisms are benefited to each other.

Which one of the following organism used as a biofertilizer is free living and never shows symbiosis ?
1 Mycorrhiza
2 Azotobacter
3 Anabaena
4 Rhizobium
Explanation:
Azotobacter is non symbiotic, free living nitrogen fixing bacteria of soil, which increase fertility of soil and hence yield of crop plants.

Best biofertilizer for paddy fields is
1 Rhizobium
2 Azolla
3 Anthoceros
4 Bacillus polymyxa
Explanation:
Azolla is a fresh water fern, coexist with rice plants. Leaves of Azolla contain cyanobacteria Anabaena which fixes atmospheric nitrogen. Azolla Anabaena symbiotic association is main biofertilizer for paddy fields. It can increase rice production up to $50 \%$.

Mycorrhizal association of which plant enables it to utilize amino acid as $\mathrm{N}$-source?
1 Strawberry
2 Cranberry
3 Orchids
4 Pinus
Explanation:
Orchids are a type of plant that has a symbiotic relationship with mycorrhizal fungi. These fungi help the orchid to absorb nutrients from the soil, including nitrogen from amino acids. Orchids are unable to absorb nitrogen directly from the soil, so they rely on their mycorrhizal partners to help them get this essential nutrient.
