Question

Pulses are rich in protein because of _____________

• A. Insectivorous habit
• B. High requirement of nitrogen fertilizers.
• C. Rhizobium
• D. Green manuring

Answer 1

Answer: (C)

Rhizobium

Pulses or legumes belong to the family of leguminous plants. Leguminous plants need a rich supply of nitrogen for the production of high protein content. Since nitrogen present in the atmosphere is not readily available, leguminous plants establish a symbiotic association with a bacteria called Rhizobium. Rhizobium helps in fixing atmospheric nitrogen into usable nitrogenous compounds. In exchange, the plant provides the bacteria with food and shelter.

So, the correct answer is option C.
