Morphology of Flowering Plants Chapter-Wise Test 2

Correct answer Carries: 4.

Wrong Answer Carries: -1.

Which of the following statements about phyllotaxy is incorrect?

Sunflower exhibits alternate phyllotaxy
Guava has opposite phyllotaxy
Alstonia shows whorled phyllotaxy
All plants exhibit opposite phyllotaxy
4

Not all plants exhibit opposite phyllotaxy. Some have alternate or whorled arrangements.

In which type of placentation are ovules attached to the central axis of a multilocular ovary?

Marginal
Axile
Parietal
Basal
2

Axile placentation occurs when ovules are attached to the central axis, as seen in tomato and china rose.

Which of the following statements about phyllotaxy is incorrect?

Sunflower exhibits alternate phyllotaxy
Guava has opposite phyllotaxy
Alstonia shows whorled phyllotaxy
All plants have whorled phyllotaxy
4

Not all plants exhibit whorled phyllotaxy. It is found only in certain plants like Alstonia.

Which of the following statements about floral symmetry is correct?

Actinomorphic flowers have radial symmetry
Zygomorphic flowers can be divided into equal halves in any plane
All flowers exhibit actinomorphic symmetry
Asymmetric flowers are the most common type
1

Actinomorphic flowers, like mustard and datura, can be divided into two equal halves in multiple planes.

Which of the following statements about root modifications is correct?

Taproots never store food
Fibrous roots are common in monocots
Pneumatophores absorb nutrients from the soil
Stilt roots are a type of underground root
2

Fibrous roots are commonly found in monocots, where they arise from the stem base and spread out near the soil surface.

Which of the following statements about inflorescence is incorrect?

Racemose inflorescence has acropetal flower arrangement
Cymose inflorescence has a continuously growing main axis
Umbel is a type of racemose inflorescence
Spadix is found in banana and maize
2

In cymose inflorescence, the main axis terminates in a flower and does not grow continuously.

Which of the following statements about stem modifications is correct?

Rhizomes are underground modified stems
Bulbs perform photosynthesis
Tendrils in pumpkins are modified leaves
Thorns are a characteristic feature of monocots
1

Rhizomes are underground stems that store food and help in vegetative propagation, as seen in ginger.

What would happen if the root cap of a growing root is removed?

Root growth would accelerate
Root hairs would elongate more
The root tip would get damaged while penetrating the soil
Lateral roots would stop developing
3

The root cap protects the delicate meristematic region of the root from mechanical damage as it pushes through the soil.

Which of the following statements about placentation is incorrect?

Axile placentation is found in China rose
Parietal placentation occurs in mustard
Basal placentation is found in sunflower
Marginal placentation is seen in tomato
4

Marginal placentation is found in pea, not in tomato. Tomato exhibits axile placentation.

Which of the following statements about flower symmetry is correct?

Zygomorphic flowers can be divided into two equal halves in multiple planes
Actinomorphic flowers have bilateral symmetry
Pea flowers exhibit zygomorphic symmetry
Sunflower flowers are zygomorphic
3

Pea flowers are zygomorphic, meaning they can be divided into two equal halves in only one plane.
