Caption

Scanning electron micrograph (SEM) of a seed of the greenhouse & houseplant, Begonia rex, popular for its colourful foliage. A tiny seed ("dust seed"), there are 1 million to the ounce (28 grams), each containing an embryo & its food supply (endosperm) awaiting conditions for germination. It is thought that the decorative exteriors, the pits & ridges, increase the chances of germination. Soil particles become trapped in the spaces so that when the seed falls on damp ground the additional weight anchors it suffic- iently for germination to procede. Magnification: X 46 at 35mm size, X 320 at 10x8-inch size.
