thats gay, my bio teacher once said that "phagocytosis" is more accurate than "endocytosis", when its ANY solid grrrrrrr......

Types
There are three main types of endocytosis that are distinguished by the size of the vesicle formed and the cellular machinery involved.
Phagocytosis (literally, cell-eating) is the process by which cells ingest large objects, such as cells which have undergone apoptosis, bacteria, or viruses. The membrane invaginates enclosing the wanted particles in a pocket, then engulfs the object by pinching it off, and the object is sealed off into a large vacuole known as a phagosome.
Pinocytosis (literally, cell-drinking). This process is concerned with the uptake of solutes and single molecules such as proteins. Both phagocytosis and pinocytosis are non-receptor-mediated forms of endocytosis, and may result in the cell engulfing non-specific or unwanted particles.
Receptor-mediated endocytosis is a more specific active event where the cytoplasm membrane folds inward to form coated pits. In this case, proteins or other trigger particles lock into receptors/ ligands in the cell’s plasma membrane. It is then, and only then that the particles are engulfed. These inward budding vesicles bud to form cytoplasmic vesicles. This process may also result in engulfing of unwanted particles, however not to the extent of pino/phagocytosis.
