Question

Ovary is half-inferior in the flowers of
A)Cucumber
B)Guava
C)Plum
D)Brinjal

Answer 1

Hint: In botany, the ovary is an expanded basal part of the pistil, the female floral gland. The ovary produces ovules, which, upon fertilization, grow into seeds. The ovary itself will grow into a fruit enclosing the seeds, either dry or fleshy.

Complete answer:
The ovary in the flowers of a plum is half-inferior. The receptacle is embedded or surrounded by a half-inferior ovary. Flowers such as these are called perigynous or half-epigynous. Half-inferior ovaries are not known in some classifications and are classified with either the dominant or inferior ovaries instead.
If sepals, petals and stamens are inserted under the ovary, the flower is considered to be hypogynous. The thalamus forms a cup-shaped structure around the ovary in perigynous flowers, and sepals, petals, and stamens tend to be inserted on the cup surface. The flower is said to be epigynous as the thalamus fully encloses the ovary and fuses with the ovary wall and sepals, petals and stamens appear to emerge above the ovary.

The anther is the end of the stamen where the pollen is found. Three sections are made of the pistil: the ovary, the style and the stigma. In order to produce a seed, the ovary produces ovules that need to be fertilized. An egg nucleus and polar nuclei are found in the ovules.

Hence, the correct answer is option (C)

Note: Fruits are graded according to the structure from which they come. There are four kinds of fruits: plain, aggregate, several, and accessory. From one single ovary of a single flower, simple fruits grow and can be fleshy or dry.
