Question

Variation in lengths of filaments of stamens within a flower is seen in:

• A. Salvinia and Brassica
• B. Brassica and Musa
• C. Salvia and Brassica
• D. Salvia and Datura

Hint:

Variations in stamen lengths include: - Tetradynamous (Brassica) - Four long, two short stamens. - Heterostyly (Salvia) - Stamens of different lengths promote cross-pollination.

Answer 1

The Correct Option is C

Step 1: Understanding Stamen Filament Variation
- Salvia exhibits heterostyly, where stamens have different lengths.
- Brassica exhibits tetradynamous condition, where four stamens are longer than the other two.

Step 2: Identifying the Correct Answer
- Salvia and Brassica exhibit different lengths of stamens, making option (3) correct.
