Question

Floral formula of Solanum nigrum:

• A.

  

• B.

  

• C.

  

• D.

  

Hint:

Floral formulas summarize floral structures. In Solanaceae, the formula typically follows: \( K_{(5)} C_{(5)} A_{(5)} G_{(2)} \).

Answer 1

The Correct Option is B

Step 1: Understanding the Floral Formula of Solanum nigrum Solanum nigrum belongs to the Solanaceae family. Its floral characteristics are: 
- Bracteate (Br) 
- Ebracteolate (Ebr) 
- Actinomorphic (Radial symmetry, \(\oplus\))
- Calyx (K) with 5 fused sepals - Corolla (C) with 5 fused petals 
- Androecium (A) with 5 epipetalous stamens 
- Gynoecium (G) with a bicarpellary ovary (2 fused carpels) 

Step 2: Identifying the Correct Answer The correct floral formula is: \[ Br \, Ebr \, \oplus \, K_{(5)} \, C_{(5)} \, A_{(5)} \, G_{(2)} \]
