Given below are two statements: Statement I : In a floral formula the symbol [percentage/division-type symbol] stands for zygomorphic nature of the flower, and G with a bar above it stands for inferior ovary. Statement II : In a floral formula the symbol [same symbol] stands for actinomorphic nature of the flower and G with a bar below it stands for superior ovary. In the light of the above statements, choose the correct answer from the options given below: (NEET 2025)
Answer: (B) Statement I is incorrect but Statement II is correct. In NCERT's floral-formula notation the symbol ⊕ stands for an actinomorphic flower (not zygomorphic), and a line drawn ABOVE G denotes an inferior ovary while a line BELOW G denotes a superior ovary.
- A.Statement I is correct but Statement II is incorrect
- B.Statement I is incorrect but Statement II is correct✓
- C.Both Statement I and Statement II are correct
- D.Both Statement I and Statement II are incorrect
Correct Answer
(B) Statement I is incorrect but Statement II is correct
Solution & Explanation
In NCERT's floral-formula notation the symbol ⊕ stands for an actinomorphic flower (not zygomorphic), and a line drawn ABOVE G denotes an inferior ovary while a line BELOW G denotes a superior ovary. Statement I is therefore wrong on the symbol's meaning (it calls ⊕ zygomorphic), so it is incorrect. Statement II correctly assigns ⊕ to actinomorphic and the bar-below-G to a superior ovary, so it is correct. Hence Statement I is incorrect but Statement II is correct (option b).
