They all have chromosome disorders (irregular number, extra or missing chromosomes)
Exocytosis occurred, where a vesicle or liposome is transported through the cell's cytoskeleton to the cell surface membrane to fuse with it, releasing the contents from within the vesicle and into the extracellular environment.
It does not matter if the vesicle or liposome had previously fused with a lysosome previously.
So long as it is a vesicle/liposome, which has a phospholipid bilayer membrane (I.e. the same as the cell surface membrane), and fusion occurs, it is exocytosis.
Hope this helps! :)
Epithelial cells also carry out active transport.
Hope this helps.
