Dandelion flower, light micrograph
Dandelion flower. Light micrograph of a section through a flower from a dandelion (Taraxacum officinalis) plant. The flower stem (bottom) is made up of parenchyma cells (light blue) with veins (purple). The flowerhead is enclosed by an outer involucre of bracts. The top of the receptacle is covered by masses of small flowers (florets), with bracts around them, the capitulum. Each floret has a bract at the base and an ovary (blue), inside which is the ovule (purple). Around the top of each ovary is a pappus of hairs (pink), that develop into the familiar parachutes. Also at the top of the ovary is the long tubular corolla (dark blue) made up of five toothed-petals. Each anther has four pollen sacs (blue circles) with pollen grains (red). The two stigmas

EDITORS COMMENTS
This stunning print captures the intricate beauty of a dandelion flower at a microscopic level. The image showcases a section through the flower, revealing its complex structure and various components. At the bottom of the flower stem, we can see parenchyma cells in light blue, intertwined with purple veins that provide support and transport nutrients throughout the plant. Surrounding the flowerhead is an outer involucre made up of bracts, adding an additional layer of protection. The top part of each floret within the flowerhead is adorned with delicate bracts and features an ovary in blue color. Inside this ovary lies a tiny purple ovule, which holds great potential for future growth. One striking feature visible in this micrograph is the pappus of hairs surrounding each ovary's top region. These hairs eventually develop into parachutes that aid in seed dispersal when they detach from their parent plant. The long tubular corolla crowning each floret exhibits five toothed-petals in dark blue hue, creating an alluring visual contrast against other elements. Furthermore, we can observe pollen grains within four pollen sacs located on each anther. This reproductive structure plays a crucial role in pollination and subsequent seed production. Overall, this image provides us with a glimpse into the fascinating world of botany and highlights nature's remarkable intricacy even at its tiniest scale.
