Dear Kritika, A flower that contain the both male (stamen) and female (pistil) reproductive structure is called a bisexual flower. 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.

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. With this structure, China rose is structured as a Bisexual flower. 

Hello Kritika

Yes, China rose is a bisexual flower.
Sweet pea and mustard are the other examples of bisexual flowers.

Good Luck!
