   Answer: B — A-IV, B-III, C-I, D-II

   Marginal placentation is seen in Pea (IV). Axile placentation is seen in Tomato (II). Parietal placentation is seen in Argemone (I). Free central placentation is seen in Primrose (III). So A-IV, B-II, C-I, D-III.

3. Q3NEET 2026Characteristics of Solanaceae Family

   Which of the following are characteristic features of Solanaceae family? (a) Flowers are bisexual and actinomorphic (b) Calyx have five sepals and are united (c) Androecium have five stamens and are epipetalous (d) Ovary is inferior Choose the correct answer from the options given below:

   • A. (d) only
   • B. (a) and (b) only
   • C. (b), (c) and (d) only
   • D. (a), (b) and (c) only
   Show answer

   Answer: C — (b), (c) and (d) only

   In Solanaceae, flowers are bisexual and actinomorphic (regular) -- (a) correct. The calyx has five sepals, gamosepalous (united) -- (b) correct. The androecium has five stamens, epipetalous (attached to the petals) -- (c) correct. The ovary in Solanaceae is SUPERIOR, not inferior -- (d) is incorrect. So (a), (b) and (c) only.

4. Q4NEET 2026Inflorescence type (racemose)

   In racemose inflorescence, ___________.

   • A. the growth is limited
   • B. flowers are solitary
   • C. flowers are borne in an acropetal succession
   • D. the main axis terminates in a flower
   Show answer

   Answer: B — flowers are solitary

   In racemose inflorescence, the main axis continues to grow (unlimited growth) and flowers are borne in acropetal succession (youngest near the apex).

5. Q5NEET 2026Region of root hair origin

   In angiosperms, root hairs arise from which one of the following regions of the root?

   • A. The region of elongation
   • B. The region of meristematic activity
   • C. The region of maturation
   • D. The root cap zone
   Show answer

   Answer: B — The region of meristematic activity

   Root hairs arise from the region of maturation (differentiation) of the root.

6. Q6NEET 2026Floral formula of Solanaceae

   Which of the following floral formula is the correct floral formula of Solanaceae family?

   • A. ⊕ ♂ K(5) C(5) A5 G(2)
   • B. ⊕ ♂ K5 C5 A5 G(2)
   • C. ⊕ ⚥ K(5) C(5) A5 G(2)
   • D. ⊕ ⚥ K5 C(5) A5 G(2)
   Show answer

   Answer: B — ⊕ ♂ K5 C5 A5 G(2)

   Solanaceae floral formula: actinomorphic, bisexual, K(5) C(5) A5 G(2) with gamosepalous calyx and gamopetalous corolla — matching option 3.

7. Q7NEET 2025Zygomorphic Flower Symmetry

   Which of the following is an example of a zygomorphic flower?

   • A. Petunia
   • B. Datura
   • C. Pea
   • D. Chilli
   Show answer

   Answer: B — Datura

   Pea flowers show zygomorphic (bilateral) symmetry, represented by the symbol %. Petunia, Datura and Chilli flowers are actinomorphic (radially symmetrical).

8. Q8NEET 2024Actinomorphic Flower Example (Datura)

   Which of the following is an example of actinomorphic flower?

   • A. Pisum
   • B. Sesbania
   • C. Datura
   • D. Cassia
   Show answer

   Answer: B — Sesbania

   Datura has an actinomorphic (radially symmetrical) flower. Pisum, Sesbania and Cassia have zygomorphic flowers. 11th NCERT Page No. 62.

9. Q9NEET 2024Flower Types - Perigynous vs Epigynous Identification from Figure

   Identify the type of flowers based on the position of calyx, corolla and androecium with respect to the ovary from the given figures (a) and (b) [Figure: two flower longitudinal sections showing different ovary positions]

   • A. (a) Perigynous; (b) Epigynous
   • B. (a) Perigynous; (b) Perigynous
   • C. (a) Epigynous; (b) Hypogynous
   • D. (a) Hypogynous; (b) Epigynous
   Show answer

   Answer: A — (a) Perigynous; (b) Epigynous

   Based on the figure, both flower (a) and flower (b) show the perigynous condition, where the ovary is in the centre and other floral parts arise from the rim of a cup-shaped thalamus at the same level. 11th NCERT Page No. 62.

10. Q10NEET 2024Types of Stamens

    Match List I with List II. List I (Types of Stamens): (A) Monoadelphous (B) Diadelphous (C) Polydelphous (D) Epiphyllous List II (Example): (I) Citrus (II) Pea (III) Lily (IV) China-rose Choose the correct answer from the options given below:

    • A. A-I, B-II, C-IV, D-III
    • B. A-III, B-I, C-IV, D-II
    • C. A-IV, B-II, C-I, D-III
    • D. A-IV, B-I, C-II, D-III
    Show answer

    Answer: B — A-III, B-I, C-IV, D-II

    Epiphyllous (attached to perianth) stamens are seen in Lily, giving D-III. Monoadelphous (filaments united into one bundle) is seen in China-rose, giving A-IV. Diadelphous (two bundles) is seen in Pea, giving B-II. Polydelphous (many bundles) is seen in Citrus, giving C-I. So A-IV, B-II, C-I, D-III is correct.
