Which of the following plants exhibits twisted aestivation in its corolla and axile placentation in its ovary?
Options
- APea
- BTomato
- CCassia
- DChina rose
Correct answer
D. China rose
Step-by-step solution
Twisted aestivation is seen in plants where one margin of the appendage overlaps that of the next one, and so on. Examples include China rose, lady's finger, and cotton. Axile placentation occurs when the placenta is axial and the ovules are attached to it in a multilocular ovary. Examples include China rose, tomato, and lemon. Therefore, China rose exhibits both twisted aestivation and axile placentation. Pea has vexillary aestivation and marginal placentation. Tomato has valvate aestivation and axile placentation
