Caption: 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.
