Final answer:
The true statement about lysosomes is that they digest cellular waste. They contain digestive enzymes that break down unwanted cellular components, contributing to cell maintenance and defense.
Step-by-step explanation:
The correct answer is c) They digest cellular waste.Lysosomes are membrane-bound organelles found in animal cells responsible for breaking down various types of materials. They contain digestive enzymes that enable them to process cellular debris, malfunctioning components, and waste materials. This function is essential to maintain cellular health by preventing the accumulation of unwanted substances, which could be detrimental to the cell. Additionally, lysosomes play a role in autophagy, the process where a cell digests its own structures as part of turnover or in response to starvation. The enzymes within lysosomes are capable of breaking down proteins, polysaccharides, lipids, and nucleic acids. Notably, lysosomes are formed by the Golgi apparatus and are sometimes referred to as the cell's "garbage disposal." They are also involved in the degradation of invading organisms such as bacteria, a process which is vital for the immune defense.
