Which two whorls of a typical flower are the non-essential or accessory whorls that do not directly take part in reproduction?
AAndroecium and gynoecium
BCalyx and corolla
CStamens and carpels
DAnther and ovary
Answer & Solution
Correct answer: B. Calyx and corolla
1. A flower has four whorls: calyx, corolla, androecium and gynoecium.
2. The two outer whorls, calyx and corolla, are non-essential or accessory because they do not directly take part in reproduction.
3. Androecium and gynoecium (with their stamens and carpels) are the essential whorls, so those options are ruled out.
4. Anther and ovary are parts within the essential whorls, so that option is wrong.
