Four Floral Whorls Structure — NEET Biology
📚 Practice ConceptEach flower normally has four floral whorls, viz., calyx, corolla, androecium and gynoecium.
Which of the following statements about floral whorls and their characteristics is/are correct? S1: Calyx and corolla are classified as accessory organs because they directly participate in sexual reproduction. S2: The perianth is a term used when the calyx and corolla are not distinct, as observed in flowers like lily. S3: Sepals, which constitute the calyx, are typically green and leaf-like, primarily functioning to protect the flower in its bud stage. S4: Petals, forming the corolla, are usually brightly coloured to attract insects for pollination. S5: Androecium and gynoecium are considered reproductive organs, essential for the production of gametes.

Correct answer: B — S2, S3, S4 and S5 are correct
Let's evaluate each statement: S1: Calyx and corolla are accessory organs, but they do not directly participate in sexual reproduction. They support the reproductive organs. This statement is incorrect. S2: Perianth is indeed the term used when calyx and corolla are not distinct, and lily is a classic example. This statement is correct. S3: Sepals are generally green, leaf-like, and their primary function is to protect the flower in the bud stage. This statement is correct. S4: Petals are usually brightly coloured and serve to attract insects for pollination. This statement is correct. S5: Androecium and gynoecium are the male and female reproductive organs, respectively, directly involved in sexual reproduction and gamete formation. This statement is correct. Therefore, statements S2, S3, S4, and S5 are correct.
