NEET 2026 (Phase 1) · BiologySolanaceaePrevious Year Question

Identify the correct floral formula of family Solanaceae. (a) ⊕ ⚥ K5 C5 A5 G(2) (sepals & petals free) (b) ⊕ ⚥ K(5) C(5) A5 G(2) (gamosepalous, gamopetalous, epipetalous, ovary superior bicarpellary) (c) % ⚥ K(5) C1+2+(2) A(9)+1 G1 (d) ⊕ ⚥ P(3+3) A(3+3) G(3) (NEET 2026)

  1. A.⊕ ⚥ K5 C5 A5 G(2)
  2. B.⊕ ⚥ K(5) C(5) A5 G(2)
  3. C.% ⚥ K(5) C1+2+(2) A(9)+1 G1
  4. D.⊕ ⚥ P(3+3) A(3+3) G(3)

Correct Answer

(B) ⊕ ⚥ K(5) C(5) A5 G(2)

Solution & Explanation

The Solanaceae flower is actinomorphic and bisexual with five united sepals and five united petals, five epipetalous stamens, and a bicarpellary syncarpous superior ovary, giving the floral formula ⊕ K(5) C(5) A5 G(2). The option showing this actinomorphic, gamosepalous and gamopetalous (fused) pentamerous formula with epipetalous stamens is the correct one (option 2 = B). NCERT Reference: Ch 5, p.69, line(s) 5-10 — "Flower: bisexual, actinomorphic"
