Why (D) is correct: A flower typically consists of four main whorls arranged concentrically on the thalamus (or receptacle). These are the calyx (sepals), corolla (petals), androecium (stamens), and gynoecium (carpels/pistil). The pedicel is the stalk that supports the flower, but it is not considered a floral whorl itself.
Why other options are wrong:
- (A) calyx: The calyx is the outermost whorl, made of sepals, and is a floral whorl.
- (B) corolla: The corolla is the second whorl, made of petals, and is a floral whorl.
- (C) androecium: The androecium is the third whorl, made of stamens (male reproductive parts), and is a floral whorl.
Common Mistake: Students sometimes confuse the supporting structures like the pedicel or bracts with the actual floral whorls.
NEET Tip / Mnemonic: Remember the four whorls from outside to inside: Calyx, Corolla, Androecium, Gynoecium (CCAG).
Correct Answer: (D)
pedicel.
