Endocytosis is the process of internalisation of substances into the cell. The substance gets surrounded by the cell membrane and then buds off inside the cell forming a vesicle. Pinocytosis and phagocytosis are types of endocytosis. Amoeba engulfs its food by the process of endocytosis with the help of pseudopodia.
- The receptor-mediated endocytosis takes place when the particular molecule in fluids wrapping cells associated with specialized receptors in the plasma membrane.
- As seen in the pinocytosis, the plasma membrane folds inwards and forms a vesicle.
