In Solanaceae family, calyx (sepals) remains persistent after fertilisation. Some examples are potato, tomato, brinjal,chilly. Guava, tomato, brinjal are the examples in which sepals remain attached after fertilization.

**Introduction:**

There are several plants in which the sepals remain attached, but one notable example is the rose (Rosa spp.). The rose is a flowering plant that belongs to the family Rosaceae. It is a popular ornamental plant known for its beautiful and fragrant flowers. The sepals of the rose flower are typically green in color and enclose and protect the developing bud. Unlike many other plants, the sepals of the rose flower do not fall off after the bud opens, but rather remain attached to the base of the flower.

**Explanation:**

The sepals are the outermost whorl of floral organs and are usually green in color. They are responsible for protecting the developing flower bud and are usually shed once the flower opens. However, in the case of roses, the sepals do not detach from the flower after blooming. Instead, they persist and remain attached to the base of the flower.

**Reasons for the Sepals Remaining Attached:**

1. **Protection:** One possible reason for the sepals of roses remaining attached is to provide continued protection to the flower. The sepals act as a barrier against physical damage, pests, and diseases.

2. **Aesthetics:** The persistent sepals of roses also contribute to the overall appearance and aesthetic appeal of the flower. They add volume and depth, enhancing the visual appeal of the bloom.

3. **Support:** The sepals of roses also provide support to the petals and other floral organs. By remaining attached, they help maintain the structural integrity of the flower.

4. **Pollination:** Another reason for the sepals remaining attached could be related to pollination. The sepals may play a role in attracting pollinators by providing additional visual cues or serving as landing platforms.

**Conclusion:**

The rose is an example of a plant in which the sepals remain attached. The persistent sepals of roses provide protection, support, and aesthetic appeal to the flower. While the specific reasons for the sepals remaining attached may vary, they contribute to the overall function and beauty of the rose flower.
