The edible part of groundnut is buried in the soil and morphologically it is a

  1. Root

  2. Stern

  3. Fruit

  4. Leaf
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • Groundnut produces lomentum fruits which s a type of indehiscent legume fruit that breaks apart at constrictions occurring between segments so that each segment contains one seed. It is a type of schizocarp. 
The fruit is geocarpic and thus ripens inside the soil itself. The pericarp of the fruit is hard but the seeds are edible. Root, stem and leaf of groundnut are not edible.
  • So, the correct answer is 'Fruit'

A diagnostic feature for identification of pea (Fabaceae) flower is

  1. Tetradynamous stamens

  2. Inferior ovary

  3. Cruciform corolla

  4. Vexillary aestivation in petals
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Fabaceae is a family that was earlier called Papilionoideae and a subfamily Leguminosae. In this type of flower five petals called polypetalous, aestivation descending imbricate or vexillary. In vexillary aestivation, there are five petals. The largest petal (called standard) overlaps the two lateral petals (called wings) which further overlap the two smallest anterior petals (called keel).
So, the correct answer is 'Vexillary aestivation in petals'.

Read the following four statements (A - D):
(A) Zygomorphic flowers are found in Fabaceae family.
(B) Monoadelphous stamens are found in Fabaceae family.
(C) Papilionaceous corolla is found in Fabaceae family.
(D) Inferior ovary is found in Fabaceae family.
How many of the above statements are wrong?

  1. Four

  2. One

  3. Two

  4. Three
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • In Fabaceae, the stamens are united into two bundles. Hence they are diadelphous. Hence statement (B) is wrong because diadelphous stamens are found in the Fabaceae family.
  • In Fabaceae, Hypogynous flowers are seen i.e the gynoecium occupies the highest position while the other parts are situated below it. The ovary in such flowers is said to be superior. Hence statement (D) is wrong because Superior ovary is found in the Fabaceae family.
  • Hence from the given 4 statements, two are wrong statements i.e statement (B) and (D).
  • So, the correct answer is 'Two'.

Which family yields poor man's protein?

  1. Papilionaceae

  2. Cruciferae

  3. Solanaceae

  4. Mimosoideae
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Poor man's protein comes from the family Papilionaceae of the flowering plants. Also known as Fabaceae or Leguminosae, these are commonly referred to as the legume or the pea family and are economically very important. This family with its extraordinary diversity of legumes there is a wide variety of edible vegetables provide to make up the protein content in the daily food basket. 

Therefore, the correct answer is option A.

Given below are the names of plants: 
Indigofera, Sesbania, Lupinus, Glycyrhiza ,Glycine max ,Crotolaria 
how many of these plant possess diadelphous stamens:

  1. Six

  2. Four

  3. Three

  4. Two
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

 Stamens are the male reproductive part of a flower, it consists of anther and filament. They are of two types:

  1. Monadelphous stamens are stamens that are present in one group, all the filaments are attached tother.
  2. Diadelphous stamens are stamens that are present in two bundles and filaments are attached together.
Many members of the family Fabaceae commonly have diadelphous stamens. E.g.; Indigofera, Sesbania, Lupinus, Glycyrrhiza, Glycine max, Crotolaria  have diadelphous stamens, present in the form of two bundles. The total number of stamens is 10 so one group has 1 stamen while another group has 9 stamens.
So, the correct option is 'Six'

Major source of protein is

  1. Oryza sativa

  2. Cicer arietinum

  3. Beta vulgaris

  4. Rhizobium leguminosarum
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The chickpea (Cicer arietinum) is a legume of the family Fabaceae, subfamily Faboideae. It is also known as gram or Bengal gram, garbanzo or garbanzo bean and sometimes known as Egyptian pea, ceci, cece or chana. Its seeds are high in protein. Chickpeas are a nutrient-dense food, providing rich content of protein, dietary fibre, folate, and certain dietary minerals such as iron and phosphorus. Thiamin, vitamin B6, magnesium and zinc contents are moderate. Chickpeas have a Protein Digestibility Corrected Amino Acid Score of about 76 percent, which is higher than fruits, vegetables, many other legumes, and cereals. So, major source of protein is Cicer arietinum compared to Oryza sativa (rice), Beta vulgaris (beet root) and Rhizobium (bacteria). 
Thus, the correct answer is option B.

  1. Cruciferae

  2. Solanaceae

  3. Compositae

  4. Polygonaceae
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Ochreate stipules occur in the family Polygonaceae. The lateral appendages present at the leaf base are called as stipules. Stipules show wide range of structural diversity. Ochreate stipules form when the two stipule are fused to form a tube like structure. Main function of stipules is to protect the leaf in the bud. 

Thus, the correct answer is option C.
