The Parts of a China Rose Flower

By CLAIRE JAMESON

The China rose is a type of hibiscus that is native to Asia, particularly the warm or tropical areas of the continent. The flowers of China roses grow up to eight inches in diameter and are trumpet shaped. The flowers have several unique characteristics that separate them from other members of genus hibiscus, including arrangement of flower components and the number of petals.

China roses have distinctive petals.

Pistil

The pistil, regarded as the "female" part of the flower, consists of the stigma, style, ovary, and ovules. In a China rose, the pistil is prominent and centrally located. The style is the very top of the pistil and is slightly sticky in order to allow pollen grains to adhere. Once trapped, the pollen grains move down the tubelike style to the round ovary, which contains the ovules. The ovules and pollen grains fuse to form the precursor to another plant.

Stamen

The stamen is the "male" part of the China rose and consists of the anthers and filaments. The anthers contain yellow pollen grains and are located atop the stalklike filaments. In a China rose, the filaments are fused in a bundle around the style, while the anthers remain unbound and encircle the stigma. The fact that the filaments are fused and the anthers are free makes the China rose a monadelphous plant.

Petals and Sepals

Although China roses are capable of self-pollination, each flower has five large, flat petals that are brightly colored to attract pollinators. The pistil and stamen project beyond the plane of the petals to allow for pollination by flying insects and birds. The petals of China roses have overlapping edges, this is called a contorted arrangement and gives the flowers their characteristic trumpet shape. The sepals are small leaflike appendages that enclosed the flower when it was a bud and remain vestigally in adulthood

Answer 2

The parts of China rose are stamen, pistil, sepal, and petal.

Explanation:

• The parts of China rose can be described as:

    Stamen:

• It is the male reproductive part of the flower.
• It consists of an anther, where pollen grains develop, and a thin, long filament that transports minerals and nutrients to the anther for pollen development.
• In china rose, the stamens are united in a single bundle.

    Pistil:

• It is the female reproductive part of a flower.
• The pistil of China rose is centrally located and is prominent.
• It consists of three parts including:

1. Stigma: It is the sticky top portion of the pistil that functions to receive pollen grain.
2. Style: It is a long thin tube that functions to transport pollen from stigma to ovary.
3. Ovary: It is the region where ovules are produced. Fertilization takes place in this region.

   Sepal:

• Sepals are the small leaf-shaped structure that supports the developing buds and petals when the flower blooms.
• There are five sepals in China rose arising from the base of the flower.

   Petal:

• Petals are modified leaf-like structure which functions to protect the reproductive structure of the flower.
• It also acts as an attractive feature to attract the animals to help in the transfer of pollen followed by fertilization.
• There are five petals in China rose.
