What are the two main types of endocytosis?
Endocytosis can be divided as pinocytosis or phagocytosis. In pinocytosis small particles on the external surface of the membrane excite the invagination of the membrane inwards and vesicles full of that particles then detach from the membrane and enter the cytoplasm. In phagocytosis bigger particles on the external surface of the membrane persuade the projection of pseudopods outwards enclosing the particles; the vesicle then detaches from the membrane and enters the cytoplasm receiving the name phagosome.
