Document Summary

The region of the body that contains much of the digestive tract and sometimes part of the reproductive system; in insects, the region behind the thorax. The most abundant protein in blood plasma, important for osmotic balance and ph buffering; also, the portion of an egg that serves as the main source of nutrients and water for the embryo. In an amniote egg, an extraembryonic membrane sac that fills much of the space between the chorion and the yolk sac and stores the embryo"s nitrogenous wastes. In an amniote egg, an extraembryonic membrane that encloses the embryo, forming the amniotic cavity and secreting amniotic fluid. Which provides an aquatic environment in which the embryo develops. In females it contains the eggs: contains protein nutrients, packages waste, adults continue to mold. Arbuscular mycorrhizal fungi symbiotic association between a glomeromycete fungus and the roots of a wide range of plants, including nonvascular, nonseed and seed plants.
