Question

How are the flowers in China Rose?

Answer 1

Hint: A flower is a reproductive structure found in flowering plants that are also known as a bloom or blossom (plants of the division Magnoliophyta, also called angiosperms). A flower's biological function is to aid reproduction, usually by providing a mechanism for sperm and eggs to unite.

Complete answer:
The vegetative part of a flower, which consists of petals and associated structures in the perianth, and the reproductive or sexual parts, can be divided into two categories. Four types of structures are attached to the tip of a short stalk in a stereotypical flower. On the receptacle, each of these parts is arranged in a whorl.
Hibiscus rosa-Sinensis, also known as Chinese Hibiscus, China rose, Hawaiian Hibiscus, rose mallow, and shoeblack plant, is a tropical Hibiscus that belongs to the Hibisceae tribe of the Malvaceae family of flowering plants. It is widely cultivated in tropical and subtropical regions, but its native distribution is unknown because it is not known in the wild.
The flowers of china rose are large, showy, trumpet-shaped, have five petals, and range in color from white to pink, red, orange, peach, yellow, and purple, with a width of 4–18 cm. Flowers from different cultivars and hybrids can be single or double in appearance.
China rose flowers are actinomorphic, hypogynous, and have twisted aestivation. In any of the radial planes that pass through the center, the actinomorphic flowers can be divided into two equivalent radial halves.

They are hypogynous, which means that the gynoecium is in the highest position and the other parts are below it. They have twisted aestivation, which means one of the margins of the petal overlaps with that of the adjacent one and it continues.

Note:
Hibiscus or china rose flowers are edible and are commonly used in salads in the Pacific Islands. In addition, the flower is used as a hair preparation. In some parts of India, it's also used to shine shoes. It can also be used to determine the pH of a solution. Acidic solutions turn dark pink or magenta when the flower is used, while basic solutions turn green.
