Caption: Aster seed. Coloured scanning electron micrograph (SEM) of a seed from an aster flower (Aster sp.). The structures seen here are the cypsela (lower frame) and a large pappus (upper frame). The pappus aids in wind dispersal. The cypsela is a type of achene, a specialised dry fruit, and the actual seed is inside the cypsela. A seed contains an embryo (a fertilised ovule from which a new plant can grow), and a supply of food. Seed dispersal methods include being carried by the wind, or water or on animal coats, or being eaten and deposited in animal droppings. Aster flowers are mostly native to Eurasia, and are a popular garden plant. Magnification: x420 when printed 10 centimetres tall.
