Question

Write a difference between
Hypogyny and Perigyny

Answer 1

Hypogyny	Perigyny
In this flower, the ovary occupies the highest position on the thalamus.	In this condition, the margin of the thalamus grows upwards to form a cup-shaped structure called a calyx tube enclosing the ovary.
Here, the petals, sepals, and stamens are separately inserted below the ovary.	Here, other parts of the flower are  located on the rim of the thalamus almost at the same level as the ovary
The ovary in such flowers is said to be superior	The ovary here is said to be half inferior
E.g. - mustard and china rose	E.g. - Plum and rose.
