Dandelion flower head. Light micrograph of a longitudinal section through the flower head (capitulum) of a dandelion (Taraxacum officinale). The flat end of the stem, the receptacle, is at bottom (light blue). The flowers (florets) are at centre and top. The floret structures include the ovules (dark purple, across lower centre), which later develop into the seeds. Above these are the fused stamens and styles, and the future pappus hairs that will aid in wind dispersal of the seeds. Magnification: x11 when printed at 10 centimetres high.
