In an experiment lasting more than 200 years, William Beal buried twenty bottles filled with these structures, which are produced by the clade Spermatophyta. Many of them contain parts called elaiosomes that ants feed to their larvae, which promotes myrmecochory. One part of these structures is surrounded by the aleurone layer, in which gibberellins stimulate alpha-amylase secretion. In most species, these structures form from a (*) double-fertilization which involves the fusion of sperm with two polar nuclei. In angiosperms, these structures usually have a nutritious triploid part, the endosperm, and another part that may contain one or two cotyledons. They are surrounded by a coat which is broken by the radicle during germination. For 10 points, name these embryonic structures which higher plants use to reproduce.
