NEETBotanyMorphology of Flowering Plants
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): In the floral formula of the Lily family (Liliaceae), the symbol P A is used. Reason (R): The flowers of the Lily family exhibit an epipetalous condition where stamens are attached to the petals. In the light of the above statements, choose the correct answer from the options given below:
Options
- ABoth Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A)
- BBoth Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A)
- CAssertion (A) is true but Reason (R) is false
- DAssertion (A) is false but Reason (R) is true
Correct answer
C. Assertion (A) is true but Reason (R) is false
Step-by-step solution
In the Lily family (Liliaceae), the calyx and corolla are not distinct and are collectively termed as the perianth, represented by the symbol P . The stamens (androecium, A ) are attached to the perianth, which is known as the epiphyllous or epitepalous condition. This adhesion is represented by an arc drawn above the symbols of perianth and androecium ( P A ). Therefore, Assertion (A) is true. Reason (R) is false because the flowers of the Lily family exhibit an epiphyllous condition, not an epipetalous condition.
