Weekly Quiz Competition

Question 1
1 / -0

Pandanus possesses

A
Stilt roots

B
Prop roots

C
Climbing roots

D
Tuberous roots

Solution

Pandanus possesses stilt roots because pandanus needs additional support which is acquired by oblique adventitious roots which arise from the lower nodes to the ground.
So, the correct option is 'Stilt roots'.
Question 2
1 / -0

Velamen containing structures of epiphyte Vanda are

A
Stems

B
Absorbing roots

C
Hanging roots

D
Clinging roots

Solution

Velamen containing structures of epiphyte Vanda are its hanging roots because velamen is multiple epidermal layers of aerial root to protect it from the UV radiation on exposure.
So, the correct answer is 'Hanging roots'.
Question 3
1 / -0

Storage roots found in clusters at base of stem are

A
Nodulose roots

B
Annulated roots

C
Tuberous roots

D
Fasciculated roots

E
Moniliform roots

Solution

Storage roots found in clusters at the base of a stem are called fasciculated roots because the adventitious roots of the plants are modified to store food giving it a fasciculated appearance.
So, the correct option is 'Fasciculated roots'
Question 4
1 / -0

Pneumatophores are characteristic features of

A
Hydrilla

B
Typha

C
Rhizophora$$/$$ Sonneratia

D
Banyan

Solution

Pneumatophores are a characteristic feature of Rhizophora because this plant lives in saline marshy soil due to which roots require an additional mechanism for breathing.
So, the correct option is Rhizophora/ Sonneratia.
Question 5
1 / -0

Match the columns.
Column I Column II
$$1$$. Tubercular storage roots a Tinospora
$$2$$. Pneumato b Heritiera
$$3$$. Haustoria c Asparagus
$$4$$. Prop roots d Viscum
$$5$$. Assimilatory roots e Screwpine

A
$$1-c, 2-b, 3-d, 4-e, 5-a$$

B
$$1-b, 2-c, 3-d, 4-e, 5-a$$

C
$$1-c, 2-d, 3-e, 4-a, 5-b$$

D
$$1-c, 2-a, 3-b, 4-e, 5-d$$

E
$$1-e, 2-d, 3-c, 4-b, 5-a$$

Solution

1) Asparagus shows tubercular storage roots as the food is stored in its roots for perrenation
2) heritiera is called pneumatophore because it lives n waterlogged condition making the roots to develop small opening for brathing.
3) Haustoria are structures which help parasitic plants suck the nutrient and water from host like in viscum.
4) Prop roots are roots which give support to plants like screwpine so that it cans stand erect in marshy soils.
5) Assimilatory roots are roots which are green in colour enabling them to produce their own food through photosynthesis as in tinospora.
So, the correct option is '1−c,2−b,3−d,4−e,5−a'
Question 6
1 / -0

Velamen occurs in

A
Epiphytes

B
Mesophytes

C
Hydrophytes

D
Xerophytes

Solution

Velamen is the multiple epidermal layer seen in the epiphytic plants. This is because the roots are hanging freely in these plants and are needed to be protected from the UV radiation which is done by velamen.
So, the correct option is 'Epiphytes'.
Question 7
1 / -0

A swollen leaf base is called ________.

A
Pulvinus

B
Amplexicaul

C
Winged

D
Sheathing leaf base

Solution

A swollen leaf base is called as Pulvinus. This type of leaves are seen in Fabaceae family. The swelling results due to change in the turgor pressure. Night closure movement of legume leaves shows this pulvinar movement. The pulvinus protects the young axillary bud.
Thus, the correct answer is 'Pulvinus.'
Question 8
1 / -0

In Musa, the venation is

A
Unicostate reticulate

B
Unicostate parallel

C
Multicostate reticulate

D
Multicostate parallel

Solution

Venation is the arrangement of veins on the leaves. It is basically of 2 types, reticulate and parallel. Reticulate venation involves irregular distribution of veins to form a network. Parallel venation involves the veins running parallel to each other. In pinnate or unicostate venation, the lamina has a single principal vein or midrib. It produces lateral veins. In palmate or multicostate venation, lamina has more than one principal vein. In Musa, the venation is unicostate parallel.
Thus, the correct answer is 'Unicostate parallel.'
Question 9
1 / -0

Unicostate venation is called as

A
Palmate

B
Pinnate

C
Reticulate

D
Parallel

Solution

Venation is the arrangement of veins on the leaves. It is basically of 2 types, reticulate and parallel. Reticulate venation involves irregular distribution of veins to form a network. Parallel venation involves the veins running parallel to each other. Pinnate venation is also called as unicostate venation. In this, the lamina has a single principal vein or midrib. It produces lateral veins. Palmate venation is also called as multicostate venation. In this, lamina has more than one principal vein.
Thus, the correct answer is 'Pinnate.'
Question 10
1 / -0

Select the correct code. Primary root is
$$1$$. Positively geotropic
$$2$$. Positively hydrotropic
$$3$$. Negatively geotropic
$$4$$. Negatively hydrotropic.

A
$$1, 2, 3$$ correct

B
$$1, 2$$ correct

C
$$2, 4$$ correct

D
$$1, 3$$ correct
Solution
- The primary root is positively geotropic and positively hydrotropic because the roots of the plant grow downwards towards gravity and also towards the water in the soil.
So, the correct option is B.
