Spelt grain,SEM
Spelt grain. Coloured scanning electron micrograph (SEM) of spelt grain,the seeds of the spelt wheat plant (Triticum spelta). 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 develops,or during germination. Seed shapes and textures vary widely,affecting how they are dispersed from their parent plant. Dispersal methods include being carried by the wind,or water or on animal coats,or being eaten and deposited in animal droppings. Spelt is a type of wheat and was one of the first grains to be cultivated. It contains more protein than the modern bread wheats,and is high in fibre
