Hairs on sepal in rose flower
Rose sepal hairs. Coloured scanning electron micrograph (SEM) of the surface of a sepal in a Garden Rose flower Rosa sp. showing hairs. Two types of hairs (trichomes) are visible projecting from the epidermal surface of the sepal. Numerous simple hairs are seen, unbranched and unicellular. A pair of larger, erect, multicellular hairs are visible with bulbous tips. These larger hairs are associated with secreting protective chemicals against pest attack, particularly when the plant is young. The sepals (calyx) form the tough outer whorl of the flower, surrounding the more delicate petals. They enclose and protect the flower when in bud.

EDITORS COMMENTS
This print showcases the intricate details of a rose flower's sepal hairs. In this colored scanning electron micrograph (SEM), we are granted a closer look at the surface of a Garden Rose sepal, revealing two distinct types of trichomes or hairs. The first type consists of numerous simple and unbranched unicellular hairs that cover the epidermal surface. These delicate structures contribute to the overall beauty and texture of the sepal. However, it is the second type that truly captivates our attention. A pair of larger, erect, multicellular hairs with bulbous tips stand out prominently in this image. These specialized trichomes play an essential role in protecting the young plant from pest attacks by secreting chemicals with their glandular structure. The sepals themselves form a tough outer whorl surrounding the more fragile petals, serving as natural armor for budding flowers. Their primary function is to enclose and safeguard these delicate blossoms until they fully bloom. With magnifications ranging from x63 at 6x9cm size to x200 at 12x27cm size, this photograph allows us to appreciate nature's intricate design on both small and large scales. It serves as a reminder of how even seemingly insignificant parts like sepals can possess remarkable features worthy of admiration in botany and plant science enthusiasts alike.
