Question

The stalk of ovule is
A) Pedicle
B) Funiculus
C) Petiolule
D) Rachiole

Answer 1

Hint: Predicted is the structure which is found at the spoof region of the plant which connects leaf to inflorescence, petiole is the stalk-like structure which is present at the basal region of leaf which connects leaf to stem. Rachelle is a long slender stalk-like structure which is found in compound leaves where all the leads are attached to this stalk by means of petiole which later connects to the stem.

Complete answer:
Ovule is the female gamete producing region within a flower, they may be more than one and forms attached to placenta in the ovary. Ovary is attached to placenta in various forms some are described here,
>Axial placentation: the placenta is at the tops of the ovary as the name suggests, here the ovary is divided into two radial segments. Example of axial plantation is Hibiscus.
>Marginal placentation: it is the simplest form of plantation where the only one elongated placenta is one of the sides of the ovary. Examples of marginal placenta include Pisum.
>Free-central placentation: This type of placentation is seen in unilocular ovaries where they are derived from the axle as partitions leaving the ovules of the central axis. An example of free central placentation includes Dianthus.
>Parietal placentation: where attachment is seen in the inner ovary wall next to fused margins of unilocular ovary. Examples include Brassica.
>Superficial placentation: this type of placentation is similar to axile but the attachment is on the inner surface of a multilocular ovary. Attachment of ovary to placenta is by a slender stalk like structure which is known as funiculus.

Hence the correct answer is Option B.

Note: Funiculus is the only stalk which is found within the ovary and also only stalk inside the flower, whereas the other options mentioned above are the connecting links of leaf to stem.
