Question

Hypogynous: Slightly convex:: Perigynous: ?

Answer 1

Thalamus or the receptacle is the end of the pedicel or peduncle at which the floral organs are borne. The shape of the thalamus varies with respect to the position of the ovary. In hypogynous flowers, the ovary is superior and the thalamus is convex or swollen or dome-shaped.

A. Convex thalamus is seen in hypogynous flowers.

B. Concave thalamus is seen in perigynous flowers.

C. Flat and cup-shaped thalamus is seen in epigynous flowers.

Hence, the correct answer is 'Convex'.
