Floral Diagram & Formula — NEET Biology
✅ Asked in NEET 2025Given 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:
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:
Answer & NCERT explanation
Correct answer: D — Statement I is incorrect but Statement II is correct
Statement I is wrong: ⊕ represents actinomorphic (radial symmetry), not zygomorphic, and G represents superior ovary. Statement II is wrong: ⚥ represents bisexual flower, not actinomorphic, and G represents superior ovary, which is correct. Both statements contain errors in floral formula symbols.

Fusion is indicated by enclosing the figure within bracket and adhesion by a line drawn above the symbols of the floral parts. A floral diagram provides information about the number of parts of a flower, their arrangement and the relation they have with one another. The position of the mother axis with respect to the flower is represented by a dot on the top of the floral diagram. Calyx, corolla, androecium and gynoecium are drawn in successive whorls, calyx being the outermost and the gynoecium being in the centre. Floral formula also shows cohesion and adhesion within parts of whorls and between whorls. The floral diagram and floral formula in represents the mustard plant (Family: Brassicaceae).
NTA tests your understanding of floral formula symbols, particularly % for zygomorphic flowers, and how diagrams represent flower structure. The key concept is that floral formulas use brackets for fusion (cohesion), lines above symbols for adhesion, and specific notations for symmetry types. Students commonly confuse which symbols indicate which relationships—many forget that % indicates zygomorphic (bilateral) symmetry, not actinomorphic (radial) symmetry. To ace this: memorize that brackets = fusion, lines = adhesion, and % = zygomorphic nature. Practice reading actual floral formulas like mustard (Brassicaceae) to reinforce these symbolic meanings before attempting MCQs.
