Euphorbia seeds. Coloured scanning electron micrograph (SEM) of seeds from a Euphorbia flower (Euphorbia 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 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. Euphorbia plants are primarily found in the tropical and subtropical regions of Africa and the Americas,but also in temperate zones worldwide | |
