Question

Which one of the following organisms is correctly matched with its three characteristics?

• A. Pea- $C_3$-pathway, 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 bundle, scutellum

Answer 1

The correct option is B Tomato- twisted aestivation, axile placentation, berry

• In tomato, twisted aestivation is found in which the mode of arrangement of petals or sepals in which they overlap each other is called as twisted aestivation.
• The arrangement of ovules within the ovary is known as placentation. It may of different types, marginal, axile, parietal, basal, central and free central.
• In tomato, axile placentation is found, it means the placenta is axial and ovules are attached to it. The tomato is a berry. The berry can be defined as a fleshy fruit produced from a single flower containing one ovary.
