Questions Related to botany
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?
-
Four
-
One
-
Two
-
Three
- 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?
-
Papilionaceae
-
Cruciferae
-
Solanaceae
-
Mimosoideae
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.
Given below are the names of plants:
Indigofera, Sesbania, Lupinus, Glycyrhiza ,Glycine max ,Crotolaria
how many of these plant possess diadelphous stamens:
-
Six
-
Four
-
Three
-
Two
Stamens are the male reproductive part of a flower, it consists of anther and filament. They are of two types:
- Monadelphous stamens are stamens that are present in one group, all the filaments are attached tother.
- Diadelphous stamens are stamens that are present in two bundles and filaments are attached together.
The family Fabaceae is alternatively known as
-
Leguminosae
-
Solanaceae
-
Compositae
-
Malvaceae
The family Fabaceae is alternatively known as Leguminosae. It is one of the largest families of flowering plants, consisting of 730 genera and over 19,400 species. The Leguminosae means the legume family and refers to the type of fruit, which is dry at maturity. It serves as a source of food.
Major source of protein is
-
Oryza sativa
-
Cicer arietinum
-
Beta vulgaris
-
Rhizobium leguminosarum
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.
Ochreate stipules occur in the family
-
Cruciferae
-
Solanaceae
-
Compositae
-
Polygonaceae
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.

Leguminosae is commonly known as grain, legumes or pea family. It is important for pulses. Grain legumes are cultivated for pulses.
Seeds which are used as Jeweller's weight ______________.

-
Calotropis
-
Thespasia
The two families dominate in having maximum useful plants
-
Fabaceae and Poaceae
-
Liliaceae and Solanaceae
-
Malvaceae and Brassicaceae
-
Liliaceae and Poaceae
The Fabaceae or Leguminosae is commonly known as the legume or pea family. They are economically important family of flowering plants. The Poaceae are a large family of monocotyledonous flowering plants. The Poaceae is the fifth largest plant family. Poaceae belongs to grass family of monocotyledonous flowering plants. It produces economically useful plants such as Barley, Maize, Oats, Rice, Bamboo, Meadow-grass, Ryegrass, etc. Most of the economically important plants in Febaceae family are herbs.
