The seed contains and disperses the embryo. Around the whole seed is a layer called the seed coat. This layer may be thick or thin, depending on the species, but it often contains light-sensitive chemicals.When conditions are right -- there is appropriate light and water -- the seed coat may trigger the germination of the seed.his layer may be thick or thin, depending on the species, but it often contains light-sensitive chemicals.

A germ layer is a group of cells in an embryo that interact with each other as the embryo develops and contribute to the formation of all organs and tissues.All animals, except perhaps sponges, form two or three germ layers. The germ layers develop early in embryonic life, through the process of gastrulation.During gastrulation, a hollow cluster of cells called a blastula reorganizes into two primary germ layers: an inner layer, called endoderm, and an outer layer, called ectoderm. germ layer is a group of cells in an embryo that interact with each other as the embryo develops and contribute to the formation of all organs and tissues.
