An association between the root nodule of a leguminous plant and rhizobium sp, is known as
- commmensalism
- mycorrhiza
- parastism
-
symbiosis
The correct answer is: D
Explanation
The association between the root nodule of a leguminous plant and rhizobium sp is a symbiotic relationship that benefits both the plant and the bacteria.
Rhizobium bacteria are soil bacteria that infect the roots of leguminous plants and cause the formation of nitrogen-fixing nodules. The bacteria convert atmospheric nitrogen into ammonia, which the plant can use for growth and development. Leguminous plants on the other hand with their plant roots provide food to the rhizobia in the form of carbohydrates, such as malate and succinate.
Mycorrhiza is a symbiotic relationship between the roots of plants and fungi that benefits both organisms.
