Question

In flower (X), the gynoecium occupies the highest position while the other parts are situated below it. The ovary in such flowers is said to be Y. Choose the correct options for X and Y.

Answer 1

• Hypogynous flowers (Superior ovary): In this, the ovary occupies the highest position on the thalamus, while other floral parts are situated below it. In such flowers, the ovary is superior. E.g., China rose, mustard, etc.

• Perigynous flowers (Half inferior ovary): In this, the ovary is situated at the centre and other floral parts are arranged on the rim of the thalamus. The ovary here is said to be half inferior. E.g., plum, rose, peach.

• Epigynous flowers (Inferior ovary): In this, the thalamus grows around the ovary fusing with its wall. The other floral parts are present above the ovary. Hence, the ovary is said to be inferior. E.g., flowers of guava and cucumber.
