Question

Which one is correctly matched with its three characteristics?

• A. Pea- $C_3$, endospermic seed, vexillary aestivation
• B. Tomato- Twisted aestivation, axile placentation, berry
• C. Onion- Bulb, imbricate aestivation, axile placentation
• D. Maize-$C_3$ pathway, closed vascular bundles, scutellum

Answer 1

Answer: (C)

Onion- Bulb, imbricate aestivation, axile placentation

Onion belongs to the family Liliaceae. It shows the underground modified stem known as the bulb which is surrounded by the fleshy leaves. These fleshy leaves perform the function of the storage of the food. The flowers of the onion show imbricate aestivation, that is, overlapping of the petals and sepals does not occur regularly. The ovary is trilocular with the axile placentation. It means that the ovules are arranged on the central axis of the placenta.

Hence, the correct answer is 'Onion-Bulb, imbricate aestivation, axile placentation'
