Question

Epipetalous is the condition of
A. Adhesion stamens
B. Cohesion of stamens
C. Aestivation of petals
D. Position of sepals with respect to petals

Answer 1

Flowers are classified on the basis of attachment of stamens .In some flowers, stamens are attached to anther , in some stamens are fused to each other and in some stamens are attached to the perianth.

Complete answer: Flowers are made up of 4 whorls calyx ,corolla ,androecium and gynoecium
The calyx is the outermost whorl of the flower and is composed of green leafy sepals. The second whorl is of petals which are collectively called the corolla. Calyx and corolla together are called the perianth. The third whorl consists of stamens which are the male reproductive system and are called androecium.
Innermost is gynoecium constituting carpels, the female reproductive part of the plant. A flower has one to multiple carpels. If all the four whorls are present the flower is described as a complete flower and if any part is missing the flower is incomplete. Flowers having both androecium and gynoecium is called hermaphrodite or bisexual and the flower having only androecium or gynoecium is called unisexual
Option A: Adhesion of stamens: Stamens adhere to the petals through their filaments and this condition is called epipetalous.
Option B: Fusion or union of stamens to each other is called cohesion of stamen.
Option C: The arrangement of sepals or petals in the floral bud is called aestivation.
Option D: The arrangement of sepals and petals with respect to each other.
Hence, option A is the correct answer.

Note: Epipetalous is the condition in which filaments of stamen fuse with petals. It is called adhesion of stamen with petals. It mostly occurs in the Solanaceae family.
