Biology Question on sexual reproduction in flowering plants
In a typical complete, bisexual and hypogynous flower the arrangement of floral whorls on the thalamus from the outermost to the innermost is
A
calyx, corolla, androecium and gynoecium
B
calyx, corolla, gynoecium and androecium
C
gynoecium, androecium, corolla and calyx
D
androecium, gynoecium, corolla and calyx
Answer
calyx, corolla, androecium and gynoecium
Explanation
Solution
A typical angiospermic flower consists of four floral appendages- calyx, corolla, androecium and gynoecium. The calyx and corolla are the 2 outer whorls and they are not involved in the reproduction directly. These are known as the accessory or helping whorls. The androecium is the male whorl and the gynoecium is the female whorls. So, the correct option is 'Calyx, corolla, androecium and gynoecium'
