Detailed explanation-1: -Phagocytosis is a special form of endocytosis in which large particles such as microorganisms and dead cells are ingested via large endocytic vesicles called phagosomes.

Detailed explanation-2: -The active-transport process by which a cell surrounds a large particle, such as a large protein, and encloses the particle in a vesicle to bring the particle into the cell is called endocytosis (EN doh sie TOH sis).

Detailed explanation-3: -Endocytosis is the process of capturing a substance or particle from outside the cell by engulfing it with th e cell membr ane. The membrane folds over the substance and it becomes completely enclosed by the membrane. At this point a membrane-bound sac, or vesicle, pinches off and moves the substance into the cytosol.

Detailed explanation-4: -Endocytosis takes particles into the cell that are too large to passively cross the cell membrane. Phagocytosis is the taking in of large food particles, while pinocytosis takes in liquid particles. Receptor-mediated endocytosis uses special receptor proteins to help carry large particles across the cell membrane.

Detailed explanation-5: -Endocytosis is the process by which a cell actively takes materials inside it, whereas exocytosis is a process which is essentially the reverse of endocytosis. In this process, exudation of secretions or waste materials from the cell takes place through the plasma membrane. Q.
