The term 'ROSE PART' refers to the three main components of a rose flower. The first component is the sepals, which are the green leaf-like structures that form the outermost layer of the flower bud. The second component is the STEM, which is the main stalk of the flower and provides support for the other parts. The third component is the petals, which are the colorful, often fragrant parts of the flower that attract pollinators.
