Question

Which of the plant is not related to Leguminosae
A. Green gram
B. Saraca
C. Paddy
D. Tamarind

Answer 1

Hint: The Fabaceae or Leguminosae, commonly referred to as the legume, pea, or bean family, is an outsized and economically important family of flowering plants. Paddy belongs to the Gramineae family which also includes rice.

Complete answer: Fabaceae, Leguminosae, or Papilionaceae, commonly referred to as legume, pea, or bean family, within the Order of Fabales, is a very popular and economically useful family in the plant kingdom. It is essentially the third largest land family in terms of the number of Species. Alongside the cereals, some fruits, and tropical roots, a variety of Leguminosae is a staple human food serving as rich sources of proteins. Paddy, rice, and other monocot plants belong to the family Gramineae or Poaceae family.
In an annual competition that pitches kernel against the kernel to be named World's Best Rice, Thailand's Khao Hom mali (jasmine rice) has taken the top position.

So, the correct answer is option C. Paddy.

Note: Recent molecular and morphological evidence supports the very fact that the Fabaceae is essentially a single monophyletic family. This conclusion has been supported not only by the degree of interrelation shown by different groups within the family compared among the Leguminosae family and their closest relations but also by all the recent phylogenetic studies supporting DNA sequences.
