We find that Rhizobium forms nodules on | Class 11 Biology Chapter Mineral Nutirtion, Mineral Nutirtion NCERT Solutions

Question:

We find that Rhizobium forms nodules on the roots of leguminous plants. Also Frankia another microbe forms nitrogen fixing nodules on the roots of non-leguminous plant Alnus.
a. Can we artificially induce the property of nitrogen fixation in a plant – leguminous or non-leguminous?
b. What kind of relationship is observed between mycorrihiza and pine trees?
c. Is it necessary for a microbe to be in close association with a plant to provide mineral nutrition? Explain with the help of one example.

Answer:

Yes, we can artificially induce the property of nitrogen fixation in a plant- leguminous and non- leguminous.
Symbiotic relationship is observed between mycorrhiza and pine trees.
Yes, it is necessary for a microbe to be in close association with a plant to provide mineral nutrition.

An example of this association is the rod- shaped Rhizobium and several legume like sweet pea, garden pea etc. relationship.
