cell membrane endocytosis
During phagocytosis, the cell membrane folds around the object, engulfing it. A second type of endocytosis is pinocytosis, which comes from the Greek word for ‘drink.’ It is the process where small, dissolved substances and liquids are taken up by a cell. Pinocytosis is similar to phagocytosis.
This fusion causes the vesicle to spill its contents out of the cell. Exocytosis is important in expulsion of waste materials out of the cell and in the secretion of cellular products such as digestive enzymes or hormones. Endocytosis, on the other hand, is the process by which materials move into the cell.
In the pit area, the membrane’s interior is coated by a protein called clathrin. The coated pit deepens and seals off in the form of a coated vesicle, when there are plenty of molecules in it. These vesicles are carried into the cell along with the molecules. Main examples of endocytosis are transportation of food,
Transport into the Cell from the Plasma Membrane: Endocytosis. In this process, the material to be ingested is progressively enclosed by a small portion of the plasma membrane, which first invaginates and then pinches off to form an endocytic vesicle containing the ingested substance or particle.

Mar 13, 2017 · Another way the cell membrane can bring molecules inside it is through endocytosis. This includes phagocytosis (“cell eating”) and pinocytosis (“cell drinking”). During these processes, the cell membrane forms a depression and surrounds the particle that it is engulfing.
Endocytosis involves the removal of portions of the cell membrane for the formation of vesicles and internalization of substances. In order to maintain cell size, membrane components must be replaced. This is accomplished by the process of exocytosis.
