Lysosomes: 

• Lysosomes are organelles that contain about 40 different types of degradative hydrolytic enzymes including phosphatases, lipases, nucleases, glycosidases, proteases, phospholipases, and sulfatases.
• Lysosomes fuse with endosomes allowing degradative lysosomal enzymes to assist in the digestion of materials inside the endosome. 
• 3 types of lysosomes: endolysosome, phagolysosome, and autophagolysosome.

Endosomes:

• Endosomes are vesicles that enclose solid extracellular materials and pathogens internalized during endocytosis. 
• In addition to the internalized material, endosomes also contain nutrients. 
• Endosomes store internalized materials until they are completely digested.
• Their primary function involves internal sorting. 
• 3 types: early endosome, late endosome, and recycling endosome.
