GO:0005618 cell wall The rigid or semi-rigid envelope lying outside the cell membrane of plant, fungal, and most prokaryotic cells, maintaining their shape and protecting them from osmotic lysis. In plants it is made of cellulose and, often, lignin; in fungi it is composed largely of polysaccharides; in bacteria it is composed of peptidoglycan. 2205
GO:0070825 micropyle An external encapsulating structure part of the chorion. A single cone-shaped specialization that forms an opening in the chorion that allows sperm entry into the egg prior to fertilization. 86
GO:0030288 outer membrane-bounded periplasmic space The region between the inner (cytoplasmic or plasma) membrane and outer membrane of organisms with two membranes such as Gram negative bacteria. These periplasmic spaces are relatively thick and contain a thin cell wall. 35
GO:0042600 chorion A protective, noncellular membrane that surrounds the eggs of various animals including insects and fish. 4
GO:0009279 cell outer membrane A lipid bilayer that forms the outermost layer of the cell envelope; enriched in polysaccharide and protein; the outer leaflet of the membrane contains specific lipopolysaccharide structures. 3
