Question

Answer

China rose posses twisted aestivation in which the petals/sepals overlaps that of the next one and so on.. it is monoadelphous that is the stamens are united in one bunch, it has axile placentation(the placenta is axile and the ovules are attached to it in a multilocular ovary)... it has alternate phyllotaxy(single leaf arises at each node)... total is 4 characters

Answer

Answer

Features of China Rose:
Among the given features, four belong to China Rose. Let's analyze each feature individually to understand why they are applicable to China Rose.

- Axile Placentation:
Axile placentation refers to the arrangement of ovules along the central axis of the ovary. In China Rose, the ovules are attached to the central axis of the ovary, making it an example of axile placentation.

- Apocarpous:
Apocarpous is a condition where the carpels of a flower are free or separate from each other. In China Rose, the carpels are distinct and not fused, indicating an apocarpous condition.

- Twisted Aestivation:
Aestivation refers to the arrangement of sepals or petals in a floral bud. Twisted aestivation is a type of aestivation where the floral parts overlap each other in a twisted manner. China Rose exhibits twisted aestivation as the petals of the flower are arranged in a twisted manner in the bud.

- Diadelphous:
Diadelphous refers to the condition where the stamens are arranged in two separate bundles or groups. In China Rose, the stamens are arranged in two groups, with the filaments fused to form two bundles, making it diadelphous.

Therefore, among the given features, axile placentation, apocarpous, twisted aestivation, and diadelphous are applicable to China Rose, making a total of four features.

Summary:
- China Rose exhibits axile placentation, where ovules are attached to the central axis of the ovary.
- It displays apocarpous condition, where the carpels are separate from each other.
- The flower shows twisted aestivation, with the petals arranged in a twisted manner in the bud.
- The stamens are diadelphous, arranged in two groups.
