Answer
Exocytosis and endocytosis are similar in the following ways:
Both sets of processes are involved in active cellular transport, in both cases energy is used to power the activities, and in both sets of processes membrane-bound vesicles are the transport vehicles or carriers. At the end ,the vesicle membranes fuse with the plasma membrane for both exo- and endo- cytosis.
However, where exocytosis moves substances out of the cell, the set of endocytotic processes -
phagocytosis, receptor-mediated endocytosis and bulk-phase endocytosis - moves substances into the cell.
Work Step by Step
Exocytosis is important in removal of waste as well as in cell division, movement of neurotransmitters, and hormones.
