Caption:
Magnified 72X, this 2006 scanning electron microscopic (SEM) image depicted details of the morphologic surface characteristics of a dandelion clock, from a common dandelion, Taraxacum officinale. The clock is the filamentous puffball of seeds, arranged so as to be easily dispersed by the wind, or the breath of a curious child. In this field of view the remnants of the seed attachments are visible as small nubs protruding from a small papule. It is from these nub-like points that the parachute-equipped seeds detach, and are blown away, sometime over a distance of miles. Note that this is the first of a series of PHIL images, 8791-8796, in which the magnification is increased, thereby, providing greater and greater morphologic detail of the point of the developing seed attachments.
