The process by which fusion of part of a cell membrane occurs is/area) Cell divisionb) Endocytosisc) Exocytosisd) Virus replication
In endocytosis, the particles to be brought inside the cell invaginate into the cell around which the cell membrane fuses. In exocytosis, the intracellular content to be released into the ECF fuses to the cell membrane. Then it is packed in a vesicle formed by the cell membrane and is released to the ECF.
