Final answer:
Lysosomes, containing digestive enzymes, are complemented by the Golgi apparatus which helps form new lysosomes or enhance existing ones, both playing critical roles in cellular digestion and defense.
Step-by-step explanation:
Lysosomes and the Golgi apparatus both contain enzymes involved in cellular digestion. Lysosomes, discovered by Christian de Duve in the 1960s, are membrane-bound organelles filled with digestive enzymes to break down various particles without harming the cell's cytoplasm. The Golgi apparatus packages these enzymes, which may form new lysosomes or fuse with existing ones. These organelles are crucial for cellular processes like autophagy, where the cell digests its own components, and in white blood cells, they assist in destroying pathogens through phagocytosis.
