Class 11 NEET Biology Morphology Of Flowering Plants Questions Part 2

Concept:The floral formula of Solanaceae family consists of symbols and numbers representing flower structure.Key Fact:Solanaceae flowers are actinomorphic, bisexual, pentamerous, and show epipetalous condition with gamosepalous calyx and gamopetalous corolla.Explanation:The correct floral formula is $\oplus\; \text{♀♂}\; \mathrm{K}_{(5)}\; \mathrm{C}_{(5)}\; \mathrm{A}_{5}\; \mathrm{G}_{(2)}$.$\oplus$ means actinomorphic (radially symmetrical).$\text{♀}\text{♂}$ indicates the flower is bisexual.$\mathrm{K}_{(5)}$ represents 5 united sepals (gamosepalous).$\mathrm{C}_{(5)}$ represents 5 united petals (gamopetalous).$\mathrm{A}_{5}$ shows 5 stamens attached to petals (epipetalous).$\mathrm{G}_{(2)}$ indicates bicarpellary, syncarpous ovary with superior position.Thus, the formula correctly shows fusion in calyx and corolla as found in Solanaceae.Answer:The correct option is the one showing $\oplus\; \text{♀}\text{♂}\; \mathrm{K}_{(5)}\; \mathrm{C}_{(5)}\; \mathrm{A}_{5}\; \mathrm{G}_{(2)}$.
