Forsythia sp. flower, light micrograph
Light micrograph of a longitudinally cut Forsythia sp. flower. The two large central structures are the stamens, the male reproductive parts. Each stamen consists of a stalk-like filament and an ovoid anther, where the pollen grains are produced. The female reproductive parts of the flower, the pistil, is at the base of the flower. At the very bottom is the ovary with the style (stalk) and stigma (spherical) rising from it. Pollen grains land on the stigma and burrow down the style to the ovary where they fertilise ovum (egg) cells, that then form seeds. Magnification: x20 when printed at 15cm wide.
