Question

Ray florets have
A. Superior ovary
B. Hypogynous ovary
C. Half inferior ovary
D. Inferior ovary

Answer 1

Pre-fertilisation is the process that occurs before actual fertilization, i.e. the process that occurs before gamete fusion. Before fertilization, male and female gametes are formed during gametogenesis. Gamete transfer is the process of combining male and female gametes.

Complete answer:
Within the order Asterales, the family Asteraceae contains over 32,000 known species of flowering plants divided into over 1,900 genera. The Compositae family, also known as the aster, daisy, composite, or sunflower family, was first described in 1740. Only the Orchidaceae has more species than the Asteraceae, and it's unclear which is the larger family based on the number of extant species.
The flower heads of members of the family are made up of many small flowers called florets that are surrounded by bracts (leaflike structures). Each head has a disk floret in the shape of a bell. Ray florets, which have a strap-like shape and are sometimes reflexed, extend outwards like petals from the center (bent back).
Ray florets are neuter flowers of the Asteraceae family's capitulum inflorescence. The ovary of both the ray and disc florets is inferior. The attachment of other floral parts is below an inferior ovary. A pome is a fleshy fruit that is frequently used as an example, but some pomes (such as Pyracantha) are half-inferior ovaries. Epigynous flowers are those with smaller ovaries. The disc florets are bisexual flowers that produce seeds, while the ray florets are sterile female flowers.

As a result, the correct response is option D.'inferior ovary'.

Note:
Some species have only disk or ray florets in their flowers. On the mature fruit, the sepals have been reduced to a ring of hairs, scales, or bristles known as the pappus. An achene is a single-seeded fruit with a hard outer covering.
