The correct Answer is:
To derive the floral formula for Solanaceae (Chilli), we can follow these steps: ### Step 1: Identify the Symmetry of the Flower The flowers of the Solanaceae family are actinomorphic (radially symmetrical). This means that they can be divided into equal halves in multiple ways. **Hint:** Look for the symmetry type of the flower when determining the floral formula. ### Step 2: Determine the Bisexual Nature The flowers are bisexual, meaning they contain both male (stamens) and female (pistils) reproductive structures. **Hint:** Check if the flower has both reproductive organs to confirm its bisexual nature. ### Step 3: Analyze the Calyx The calyx consists of 5 sepals that are fused together (gamosepalous). **Hint:** Count the number of sepals and check if they are free or fused. ### Step 4: Examine the Corolla The corolla also has 5 petals that are fused (gamopetalous). **Hint:** Similar to the calyx, identify the number of petals and their arrangement. ### Step 5: Evaluate the Androecium The androecium consists of 5 stamens that are epipetalous, meaning they are attached to the petals. They are also polyandrous. **Hint:** Look for the number of stamens and their attachment to the petals. ### Step 6: Assess the Gynoecium The gynoecium is bicarpellary and syncarpous, meaning it has two fused carpels. It is also superior. **Hint:** Determine the number of carpels and whether they are fused or separate. ### Step 7: Compile the Floral Formula Based on the observations: - Symmetry: Actinomorphic - Bisexual: Yes - Calyx: 5 (gamosepalous) - Corolla: 5 (gamopetalous) - Androecium: 5 (epipetalous) - Gynoecium: 2 (superior, syncarpous) The floral formula can be written as: **Floral Formula:** \[ \text{Actinomorphic, Bisexual, Calyx: } \text{(5 fused)}, \text{ Corolla: } \text{(5 fused)}, \text{ Androecium: } \text{(5 epipetalous)}, \text{ Gynoecium: } \text{(2 superior)} \] ### Final Floral Formula for Solanaceae (Chilli) The complete floral formula can be represented as: \[ \text{(5) \text{(5)} \text{(5)} \text{(2)}} \] ### Summary of the Floral Formula The floral formula for Solanaceae (Chilli) is: **Actinomorphic, Bisexual, Calyx: 5 (fused), Corolla: 5 (fused), Androecium: 5 (epipetalous), Gynoecium: 2 (superior)**
