Which flower is considered anatomically simple?

• A. Roses
• B. Orchids
• C. Sunflowers
• D. Lilies

Answer: (D)

Anatomical simplicity in flowers means a straightforward, non-specialized arrangement of parts, with clearly recognizable petals (or tepals), stamens, and a simple pistil, without extra adaptations for particular pollinators. Lilies fit this idea: they have six tepals that look alike, six stamens, and a simple pistil, representing a basic floral blueprint. Other options show more specialized or complex features—orchids with a fused column and pollinia, or sunflowers with a composite head of many small flowers, or roses with numerous petals and a more elaborate floral structure—so lilies are the simplest in terms of anatomy.
