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): Flowers of Datura and Chilli show radial symmetry. Reason (R): When a flower can be divided into two equal radial halves in any radial plane passing through the centre, it is said to be actinomorphic. In the light of the above statements, choose the most appropriate answer from the options given be
Options
- ABoth (A) and (R) are correct and (R) is the correct explanation of (A)
- BBoth (A) and (R) are correct but (R) is not the correct explanation of (A)
- C(A) is correct but (R) is not correct
- D(A) is not correct but (R) is correct
Correct answer
A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
Step-by-step solution
Assertion (A) is correct because the flowers of Datura, Chilli, and Mustard are actinomorphic, which means they exhibit radial symmetry. Reason (R) is correct as it provides the exact botanical definition of an actinomorphic flower. Since the reason correctly defines the term (actinomorphic) that justifies why Datura and Chilli are said to have radial symmetry, (R) is the correct explanation of (A). Answer: Both (A) and (R) are correct and (R) is the correct explanation of (A)
