उत्तर
The non-essential or accessory parts of flowers are the calyx and corolla since they do not directly participate in the process of sexual reproduction leading to the development of the seed.
1) Sepals of the calyx are green, leaf-like, and protect the inner whorls of the flower in the bud stage. They are also involved in producing food by photosynthesis.
2) Petals of the corolla are usually brightly coloured to attract insects for pollination; they also protect the inner whorls.
