Morphology
exocytosis = cytosis (semi-transparent) = exo + cyto + osis
Adding the productive prefix 'exo-' to the existing biological noun 'cytosis' is regular, but the combining form 'cyto-' and the suffix '-osis' are specialized biomedical morphemes that may not be obvious to general learners.
Etymology
The word exocytosis comes from the parts exo- 'outside', cyto- 'cell', and -osis 'process'. So, exocytosis is the process when a cell sends or pushes substances out to the outside, like a tiny package leaving the cell.
