This organelle is composed of a selectively permeable phosopholipid bilayer that encloses the cytoplasm.
The exposure of phosphatidyl serine in one part of this structure is one signal of apoptosis, another of which is the formation of blebs. Flippases allow components to move throughout this structure, and integral proteins such as G-protein coupled receptors are found in this structure. In one model, this consists of rafts floating in a two-dimensional liquid; that is the fluid mosaic model of this organelle. Parts of this organelle break off during endocytosis. This organelle is composed of a selectively permeable phosopholipid bilayer that encloses the cytoplasm. For 10 points, name this organelle that surrounds the cell.
