A vacuole is a membrane-bound organelle which is present in plant and fungal cells and some protist, animal, and bacterial cells. Vacuoles are essentially enclosed compartments which are filled with w

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

…that the substances ingested are in solution and not visible under the microscope. Phagocytosis and pinocytosis are both undertaken in association with lysosomes which complete the breakdown of the material which has been engulfed. Salmonella is able to survive and reproduce in the vacuoles of several mammal…
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).
