Which term describes the arrangement of veins and veinlets in the leaf?

Placentation
Venation
Aestivation
Inflorescence
2

Venation refers to the pattern of veins in the leaf, which can be reticulate or parallel.

Which of the following describes an actinomorphic flower?

It has radial symmetry
It has bilateral symmetry
It is asymmetrical
It has no symmetry
1

Actinomorphic flowers have radial symmetry, meaning they can be divided into equal halves in multiple planes.

Which of the following statements about phyllotaxy is correct?

Whorled phyllotaxy is found in mustard
Alternate phyllotaxy is seen in sunflower
Opposite phyllotaxy is found in Alstonia
Whorled phyllotaxy is common in monocots
2

Sunflower exhibits alternate phyllotaxy, where a single leaf arises at each node in an alternating manner.

Which of the following statements about flower symmetry is correct?

Zygomorphic flowers have radial symmetry
Actinomorphic flowers have bilateral symmetry
Pea flowers are zygomorphic
Sunflower flowers are zygomorphic
3

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

Which of the following statements about fruits is incorrect?

Drupe is a fleshy fruit with a hard endocarp
Mango is a drupe
Coconut is a dry fruit
Tomato is a berry
3

Coconut is classified as a drupe, not a dry fruit, because it has a fibrous mesocarp and a hard endocarp.

In which type of inflorescence does the main axis continue to grow and flowers are borne in an acropetal succession?

Cymose
Racemose
Solitary
Basal
2

In racemose inflorescence, the main axis grows continuously, and flowers appear in acropetal succession.

Which of the following statements about leaves is incorrect?

Compound leaves have divided leaflets
The petiole connects the lamina to the stem
In grasses, the leaf blade is not differentiated into a petiole and lamina
Parallel venation is characteristic of dicot leaves
4

Parallel venation is characteristic of monocots, while dicots usually have reticulate venation.

Which of the following statements about phyllotaxy is correct?

Alternate phyllotaxy is found in guava
Whorled phyllotaxy is found in Alstonia
Opposite phyllotaxy is common in sunflower
Alternate phyllotaxy is absent in dicots
2

In Alstonia, multiple leaves grow in a whorl at each node, making it an example of whorled phyllotaxy.
