Pollen on a flower petal of a primrose (Primula veris). Several slots around the pollen grain are the germ openings (apertures, colored orange). Here the pollen tube shoots out when the pollen lands on a stigma. Primroses are used as medicinal plants because of their high saponin content in the leaves and roots. Herbal tea and juices from it are used as expectorant in colds and chronic bronchitis. In folk medicine, the blossom is also used as a nerve remedy for headaches, neuralgia, tremors, dizziness and as a cardiac tonic. Scanning electron microscope, magnification 4000x (at 15x12cm image size).
