Composite (family Compositae/Asteraceae) flower seed,coloured scanning electron micrograph (SEM). A seed contains an embryo (a fertilised ovule from which a new plant can grow),and a supply of food. Seed shapes and surface textures vary widely,affecting how they are dispersed from their parent plant. This seed has a feather-like structure called a pappus (not seen),which aids wind dispersal of the seed. Other seed dispersal methods include being carried by water or on animal coats,or being eaten and deposited in animal droppings | |
