Daisy flower. Coloured scanning electron micrograph (SEM) of the surface of a daisy flower after the seeds have been dispersed. Daisy plants (family Asteraceae, formerly Compositae) have composite flowers comprising a central area of disc florets surrounded by larger ray florets. During reproduction the disc florets are pollinated and form seeds known as cypselas. The base of one is at top left. The cypselas become detached from the daisy and are carried on the wind to new ground where they germinate. The scars (brown) show where each of the seeds was attached to the flower.
