A seed is an embryonic plant enclosed in a protective outer covering known as the seed coat. It is a characteristic of spermatophytes (gymnosperm and angiosperm plants) and the product of the ripened ovule which occurs after fertilization and some growth within the mother plant.he seed coat in the mature seed can be a paper-thin layer (e.g. peanut) or something more substantial (e.g. thick and hard in honey locust and coconut), or fleshy as in the sarcotesta of pomegranate. The seed coat helps protect the embryo from mechanical injury, predators and drying out.
Main Image: Germ layer is a collection of cells found in a prenatal embryo that will give rise to all of the bodyâs tissues and organs. Germ layer, occasionally referred to as germinal epithelium (one of the 4 basic type of animal tissue), is a group of cells, formed during animal embryogenesis. Embryogenesis is process by which the embryo is formed and develops into a fetus. Germ layers are predominantly found in vertebrates. However invertebrates also have germ layers as well, just not as many - sponges have just 1 germ layer, cnidarians (jelly fish and relatives) have 2
