A lysosome is a membrane-bound organelle that is found in all animal cells, and rarely in plant cells. There are normally hundreds of lysosomes in the cytosol, where they function as the cell's degrad

…a biomonitor to indicate pollution caused by heavy metals, organochlorides and petroleum products. Mussels that are in contaminated areas have labile lysosomal membranes due to metal-induced stress. This mussel is also notorious for clogging water pipes used by industrial complexes and fouling marine equipment…
TEM views of various vesicular compartments. Lysosomes are denoted by "Ly". They are dyed dark due to their acidity; in the center of the top image, a Golgi Apparatus can be seen, distal from the cell membrane relative to the lysosome.
Cellular material is delivered to lysosomes in four different ways: (A) Macroautophagy, (B) Endosomal degradation, (C) Microautophagy and (D) Chaperone-mediated autophagy (CMA).
