Creeping zinnia seed,SEM
Creeping zinnia seed. Coloured scanning electron micrograph (SEM) of a seed from a creeping zinnia flower (Sanvitalia sp.). A seed contains an embryo (a fertilised ovule from which a new plant can grow),and a supply of food. The food is used either while the embryo grows within the developing seed,or during germination. Seed shapes and surface textures vary widely,affecting how they are dispersed from their parent plant. Seed dispersal methods include being carried by the wind,or water or on animal coats,or being eaten and deposited in animal droppings. Creeping zinnia is a widely cultivated ornamental flowering plant
