Question

Assertion (A): In Liliaceae, flowers are homochlamydeous
Reason (R): In Liliaceae perianth is differentiated

• A. Both (A) and (R) are true, (R) is the correct explanation of (A)
• B. Both (A) and (R) are true, (R) is not the correct explanation of (A)
• C. (A) is true, but (R) is false
• D. (A) is false, but (R) is true

Hint:

Homochlamydeous = tepals (undifferentiated perianth); heterochlamydeous = distinct calyx and corolla.
Liliaceae (typical) show 6 similar tepals — remember "Lily = tepals".
For Assertion-Reason questions, check whether the reason actually contradicts or supports the assertion.

Answer 1

The Correct Option is C

1. "Homochlamydeous" means the perianth is not differentiated into distinct calyx and corolla; instead the perianth segments (tepals) are similar in appearance.
2. Liliaceae typically have a perianth made of six similar tepals (two whorls of three), i.e., a homochlamydeous perianth — so Assertion (A) is true.
3. The Reason (R) claims "perianth is differentiated" — that would mean distinct calyx and corolla (heterochlamydeous), which is not true for typical Liliaceae. Thus Reason (R) is false.
4. Therefore (A) is true and (R) is false. Hence the correct answer is (3) (A) is true, but (R) is false.
