Question

Identify the type of flowers based on the position of calyx, corolla and androecium with respect to the ovary from the given figures (a) and (b).

A

(a) Hypogynous; (b) Epigynous

B

(a) Perigynous; (b) Epigynous

C

(a) Perigynous; (b) Perigynous

D

(a) Epigynous; (b) Hypogynous

Step-by-Step Solution

book description of floral part positions on the thalamus:

  • Hypogynous: The gynoecium occupies the highest position while other parts are situated below it. The ovary is superior (e.g., mustard, china rose) .
  • Perigynous: The gynoecium is situated in the centre and other parts are on the rim of the thalamus at the same level. The ovary is half inferior (e.g., plum, rose, peach) .
  • Epigynous: The margin of the thalamus grows upward enclosing the ovary completely and fusing with it, with other parts arising above the ovary. The ovary is inferior (e.g., guava, cucumber) .

(Note: In the textbook Figure 5.9, (b) and (c) represent Perigynous and (d) represents Epigynous flowers).
