UPSC Prelims 2024 Question:

Consider the following plants

1. Groundnut
2. Horse-gram
3. Soybean
   
   

How many of the above belong to the Pea family?

Explanation:

• • The Fabaceae, or pea family, is a large group of flowering plants (angiosperms) within the order Fabales. It is the third-largest family among angiosperms, following Orchidaceae (orchid family) and Asteraceae (aster family). Fabaceae includes over 700 genera and approximately 20,000 species of trees, shrubs, vines, and herbs, distributed worldwide. Key commercial species within this family include soybeans (Glycine max), garden peas (Pisum sativum), peanuts (Arachis hypogaea), and alfalfa (Medicago sativa). While most woody species are found in tropical regions, herbaceous (nonwoody) species are primarily located in temperate areas.
    
    

• Groundnut (Arachis hypogaea) and Horse-gram (Macrotyloma unifl orum) belongs to the Fabaceae family.
  
  

So, all three of the above belong to the Pea family.

Therefore, option (3) is the correct answer.
