Castor

Vedclass · Answer

(B) The correct answer is $B$ (Castor).Nitrogen fixation is the process of converting atmospheric nitrogen into ammonia,which is primarily carried out by symbiotic bacteria like $Rhizobium$ in the root nodules of leguminous plants.Bean,Gram,and Pea are all members of the family $Fabaceae$ (legumes),which form symbiotic relationships with nitrogen-fixing bacteria.Castor ($Ricinus$ $communis$) belongs to the family $Euphorbiaceae$ and does not possess the ability to form symbiotic associations with nitrogen-fixing bacteria; therefore,it cannot fix atmospheric nitrogen directly.
