Final answer:
Lysosomes are specialized organelles within cells that contain digestive enzymes essential for breaking down various cellular materials including waste, proteins, lipids, and carbohydrates. They are part of the endomembrane system and play a key role in recycling cellular components and the immune response.
Step-by-step explanation:
The organelles that contain digestive enzymes, possess an acidic environment, remove cellular debris, and break down lipids, carbohydrates, and proteins are known as lysosomes. These membrane-bound structures are integral to the endomembrane system and function as a sort of cellular "garbage disposal." Lysosomes, with their diverse range of enzymes such as lipases, proteases, and nucleases, are crucial for autophagy, the process of cellular self-digestion. These enzymes ensure efficient digestion and recycling of cellular components, preventing damage to the cytoplasm. In addition, lysosomes play a critical role in the immune response by breaking down foreign material, including pathogens ingested by white blood cells through phagocytosis.
