"A process that is carried out at the cellular level which results in the formation, arrangement of constituent parts, or disassembly of a lysosome. A lysosome is a cytoplasmic, membrane-bounded organelle that is found in most animal cells and that contains a variety of hydrolases [goid 7040] [evidence IEA]; The directed movement of proteins into, out of, within or between cells [goid 15031] [evidence IEA]; The movement of a leukocyte in response to an external stimulus [goid 30595] [evidence ISS]; A process that is carried out at the cellular level which results in the formation, arrangement of constituent parts, or disassembly of a melanosome. A melanosome is a tissue-specific, membrane-bounded cytoplasmic organelle within which melanin pigments are synthesized and stored [goid 32438] [evidence IEA]; A process that is carried out at the cellular level which results in the formation, arrangement of constituent parts, or disassembly of a melanosome. A melanosome is a tissue-specific, membrane-bounded cytoplasmic organelle within which melanin pigments are synthesized and stored [goid 32438] [evidence ISS]; The directed movement of substances from endosomes to lysosomes by a pathway in which molecules are sorted into multivesicular bodies, which then fuse with the lysosome [goid 32510] [pmid 9606205] [evidence IMP]; A process that is carried out at the cellular level which results in the formation, arrangement of constituent parts, or disassembly of a secretory granule in a mast cell. A secretory granule is a small subcellular vesicle, surrounded by a membrane, that is formed from the Golgi apparatus and contains a highly concentrated protein destined for secretion [goid 33364] [evidence ISS]; The directed killing of a target cell by a natural killer cell through the release of granules containing cytotoxic mediators or through the engagement of death receptors [goid 42267] [pmid 10648412] [evidence IMP]; The directed killing of a target cell by a natural killer cell through the release of granules containing cytotoxic mediators or through the engagement of death receptors [goid 42267] [pmid 6154765] [evidence IMP]; Reactions triggered in response to the presence of a bacterium that act to protect the cell or organism [goid 42742] [evidence ISS]; Reactions triggered in response to the presence of a protozoan that act to protect the cell or organism [goid 42832] [evidence ISS]; The deposition or aggregation of coloring matter in an organism, tissue or cell [goid 43473] [evidence IEA]; The deposition or aggregation of coloring matter in an organism, tissue or cell [goid 43473] [pmid 10648412] [evidence IMP]; Reactions triggered in response to the presence of a virus that act to protect the cell or organism [goid 51607] [evidence ISS]"
