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:
(1) Statement I is incorrect but Statement II is correct
(2) Both Statement I and Statement II are correct
(3) Both Statement I and Statement II are incorrect
(4) Statement I is correct but Statement II is incorrect

Accepted Answer

Correct Answer: A — Statement I is incorrect but Statement II is correctStep-by-step Solution:In floral formula notation, specific symbols are used to represent floral characteristics:Statement I Analysis — INCORRECT:The symbol ⊕ (a circle with a cross/plus sign) represents actinomorphic (radially symmetric) flowers — NOT zygomorphic. Actinomorphic flowers can be divided into two equal halves by any vertical plane through the center.The symbol % represents zygomorphic (bilaterally symmetric) flowers — flowers that can be divided into two equal halves by only ONE specific vertical plane.For gynoecium: G (with a line below the number) = superior ovary; G̅ (with a line above/overline) = inferior ovary. So G alone (without an overline) indicates superior ovary, NOT inferior ovary as stated in Statement I. Statement I has TWO errors: wrong symmetry symbol AND wrong ovary position for G.Statement II Analysis — CORRECT:⊕ represents actinomorphic nature — CORRECTG (without overline/bar) represents superior ovary — CORRECT. In a superior ovary, the ovary is positioned above the attachment of floral whorls (hypogynous condition); the receptacle is below the ovary.Extended Explanation:Important floral formula symbols: Symmetry: ⊕ = actinomorphic (regular); % = zygomorphic (irregular). Sex: ⚥ = bisexual; ♂ = male (staminate); ♀ = female (pistillate). Sepals (K): K5 = 5 free sepals; K(5) = 5 fused sepals. Petals (C): C5 = 5 free petals; C(5) = 5 fused petals. Androecium (A): A∞ = many stamens; A(9)+1 = diadelphous (as in pea). Gynoecium (G): G1 = monocarpellary superior; G̅(3) = tricarpellary inferior (fused). Floral diagrams and formulas are key tools for plant family identification. Examples: Solanaceae (potato family): ⊕ ⚥ K(5) C(5) A5 G(2); Fabaceae/Papilionaceae (pea family): % ⚥ K(5) C1+2+(2) A(9)+1 G1.Key Concepts: Floral formula symbols, actinomorphic (⊕) vs zygomorphic (%), superior ovary (G) vs inferior ovary (G̅), ovary position, floral symmetry.
