Question

An epigynous flower is characterised by

• A. Inferior ovary
• B. Superior ovary
• C. Oblique ovary
• D. Half superior and half inferior ovary

Answer 1

The correct option is A

Inferior ovary

The correct option is A.

Explanation of correct option:

1. In epigynous flowers, the thalamus margin rises upward, completely encircling and fusing with the ovary; the other components of the flower ascend above the ovary.
2. The ovary of an epigynous flower, such as guava and cucumber blooms, and the ray florets of sunflowers, are considered to be inferior.

Explanation of incorrect options:

Option B:

1. Hypogynous flowers are those in which the gynoecium is at the top of the flower and the other components are below it.
2. This variety's ovary is reported to be superior to others, such as mustard, china rose, and brinjal.

Option C:

1. The term "oblique ovary" refers to an ovary that is positioned obliquely in a diagonal plane.
2. It belongs to the Solanaceae family. The gynoecium is bicarpellary and syncarpous in this case.
3. And the ovary is positioned superiorly or obliquely.

Option D:

1. Perigynous flowers are those in which the gynoecium is in the center and the other parts of the flower are virtually at the same level as the thalamus rim.
2. The ovary in perigynous flowers, such as plum roses and peaches, is considered to be half inferior and half superior.

Final answer: An epigynous flower is characterised by inferior ovary.
