Question 26 of 26

🟢 NEET 2026 📘 CLASS XI

Morphology Of Flowering Plants

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

AI-generated explanation. Check against your textbook.

Explanation:

The floral formula of Solanaceae (e.g., potato, tomato) in NCERT is pentamerous and gamopetalous with a superior, syncarpous ovary. The standard formula is K5 C5 A5 G(5) — 5 sepals (calyx), 5 petals fused into a tube (corolla), 5 stamens, and a 5-celled syncarpous ovary. Thus, option 3 is correct.

🧠 Did You Know?

Solanaceae flowers are usually regular and zygomorphic in some genera, but NCERT describes the common pentamerous, actinomorphic flowers with fused corolla in this family.

💡 NCERT Memory Line:

Solanaceae: K5 C5 A5 G(5) – pentamerous, fusion in corolla, superior syncarpous ovary.
