Option(4) Wreath
The arrangement of flowers in a circle with a central flower is known as a wreath. This structure is not to be confused with the biological flower components such as sepals and petals, which are organized into whorls like the calyx and corolla.
Explanation:
Option(4) Wreath
The arrangement of flowers in a circle with one central flower is called a wreath. Flower structure can be complex, as a typical flower consists of four main parts, or whorls, which include the calyx (sepals), corolla (petals), androecium (male reproductive structure), and gynoecium (female reproductive structure). The calyx and corolla are together known as the perianth.
The calyx helps protect the unopened bud while the corolla is usually brightly colored to attract pollinators. The number of sepals and petals varies between monocots and dicots. The androecium consists of stamens with anthers that contain the microsporangia, and the innermost group is the gynoecium, which includes the carpels, composing the female reproductive organs.
