Which term describes petals that are fused together in a flower?

• A. Gamopetalous
• B. Polypetalous
• C. Staminode
• D. Epipetalous

Answer: (A)

In flowers, you describe how the petals are arranged as either fused or free. When the petals are fused together to form a tube, cup, or ring, the term gamopetalous applies. This indicates the corolla is united at least at the base, creating a single floral limb rather than separate petals. In contrast, polypetalous means each petal stays separate and not fused with the others. The other terms refer to different features: a stamen that is sterile is called a staminode, and epipetalous describes stamens attached to petals rather than describing the fusion of the petals themselves. So the term that best describes petals fused together is gamopetalous.
