Which term describes a flower that can be divided into equal halves along any diameter?

• A. Bilateral symmetry
• B. Asymmetric
• C. Circular symmetry
• D. Radial symmetry

Answer: (D)

Radial symmetry is about how a flower is put together around a central axis so that you can draw a line through the center in any direction and still split the flower into two mirror-image halves. That property—dividing into equal halves along any diameter—is exactly what radial symmetry describes. It contrasts with bilateral symmetry, which only has one plane of division that creates matching halves, and with asymmetric flowers, which lack any line of symmetry. In botany, this arrangement is common in actinomorphic flowers, like daisies, where petals radiate around the center.
