Question

Fabaceae family is known for: ____.

• A. Nitrogen fixation
• B. Photosynthesis
• C. Respiration
• D. Fermentation

Hint:

Because of their active nitrogen-fixing relationships, plants in the Fabaceae family are rich sources of vegetable proteins and are universally preferred crops for crop rotation methods.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Certain plant families establish specialized root structural modifications to harbor beneficial soil microorganisms for nutrient uptake.

Step 2: Detailed Explanation:
The Fabaceae family (formerly Papilionaceae, commonly known as the legume, pea, or bean family) is structurally characterized by having root nodules. These nodules harbor symbiotic, nitrogen-fixing soil bacteria belonging to the genus Rhizobium. These bacteria convert inert atmospheric dinitrogen gas ($N_2$) into usable forms like ammonia ($NH_3$) for the host plant, allowing these crops to thrive in nitrogen-poor soils and enrich farmland naturally.

Step 3: Final Answer:
The Fabaceae family is known for biological nitrogen fixation.
