Question
Given below are two statements: Statement I: In a floral formula, ⊕ stands for zygomorphic nature of the flower, and G stands for inferior ovary. Statement II: In a floral formula, ⊕ stands for actinomorphic nature of the flower and G stands for superior ovary.
In the light of the above statements, choose the correct answer from the options given below:
Statement I is correct but Statement II is incorrect
Statement I is incorrect but Statement II is correct
Both Statement I and Statement II are correct
Both Statement I and Statement II are incorrect
book, in a floral formula, the symbol ⊕ stands for actinomorphic (radial symmetry) nature of the flower, while % stands for zygomorphic (bilateral symmetry). Furthermore, G with a line below it (usually represented as <u>G</u>) denotes a superior ovary, while G with a line above it (G̅) denotes an inferior ovary [Sources 69, 70]. Therefore, Statement I is incorrect because ⊕ is not zygomorphic, and Statement II is correct regarding the actinomorphic symbol and the description of the superior ovary contextually.
This question aligns with the NEET BIOLOGY syllabus, specifically targeting concepts from Morphology of Flowering Plants.
