Actinomorphic flowers exhibit which type of symmetry?

• A. Bilateral symmetry
• B. Radial symmetry
• C. No symmetry
• D. Asymmetric

Answer: (B)

Actinomorphic flowers have radial symmetry. This means the flower is regular and can be divided into mirror-image halves by any plane that passes through its center. That multi-directional symmetry lets pollinators approach from many angles. By contrast, bilateral symmetry has a single plane of symmetry, producing two equal halves, and is typical of zygomorphic flowers. Saying there is no symmetry or that the flower is asymmetric doesn’t fit actinomorphic flowers, which exhibit symmetry in all planes through the center.
