Question

Root nodules are not formed in non-leguminous plants because they grow in

• A. Nitrogen deficient soils
• B. Soils having bacteria for converting nitrogen into usable form
• C. Soils rich in nitrogen
• D. All the above

Answer 1

The correct option is B Soils having bacteria for converting nitrogen into usable form

Roots nodules are not formed in non-leguminous plants because they grow in soils having bacteria for converting nitrogen into a usable form. So, they do not need bacteria stored in the nodules to obtain nitrogen content like legumes.

So, the correct option is 'Soils having bacteria for converting nitrogen into a usable form'.
