Intracellular digestion is carried out by organelles called lysosomes. There are several contexts in which cells need to carry out digestion.
3. The organelles responsible for intracellular digestion are lysosomes. Lysosomes are vesicles that contain digestive enzymes capable of breaking down large molecules into smaller ones. These vesicles fuse with others carrying the material to be digested and, as a result, digestion takes place.
