Question

Which of the following Statement is false about Fabaceae?
A. It was earlier mentioned as Papilionoidea
B. It is widely distributed across the world
C. It is common to find plants with fibrous root systems here
D. It is a subfamily of family Leguminosae

Answer 1

Hint:
It is essential to understand the terminology of Fabaceae before moving on to the question.
The Fabaceae or Leguminosae, also referred to as the legume, pea, or bean family, is a sizable and significant group of flowering plants from the perspective of agriculture. It contains trees, shrubs, and herbaceous plants, both permanent and annual, which are distinguished by their leguminous fruit and compound, stipulate leaves. With over 765 genera and nearly 20,000 recognized species, the family is widely dispersed.

Complete step by step answer:
There are many economically significant plants in the broad plant family known as Fabaceae. Since it is a member of the pea or legume family, the Fabaceae are often referred to as Leguminosae or Papilionaceous. Worldwide, the dicotyledonous Fabaceae plant family contains about 20,000 different species.
The morphological and floral traits of the Fabaceae family are listed below.
Vegetative Creatures:
Root: A dicotyledon with a taproot and root nodule.
Stem: Erection or climb; Fabaceae contains shrubs, herbs, trees, and primarily climbers.
Leaves: Petiolate, petiolate complex or simple; pulvinus leaflet base, stipulate; tightly coiled venation.
Floral Creatures:
Inflorescence: the racemose.
Flower: Whole, zygomorphic, hypogynous, bisexual, and bracteate/ebracteate.
Calyx: Valvate or irregular aestivation, five gamosepalous petals.
Corolla: Polypetalous, papilionaceous, five-petaled, and aestivated at the vexillary apex.

Option ‘C’ is correct

Note:
The plants under this family are special because they have nitrogen-fixing symbiotic bacteria in their root nodules, which may convert atmospheric nitrogen into nitrogen fixation or ammonia. The primary source of food is pulses like gramme, moong, and soya beans. The oil used in cooking is extracted from soybeans and groundnuts. Timber and fibre are sourced from sun hemp. To manufacture dye, Indigofera is utilized.
