Define autolysis. Name the cell organelle involved in it.

Explanation

**Step-by-Step Solution:**

1. **Definition of Autolysis**:
- Autolysis is the process by which a cell self-digests or breaks down its own components. This typically occurs when the cell is old, damaged, or no longer functional. The purpose of autolysis is to remove worn-out or non-functional cell organelles and recycle their components.

2. **Cell Organelle Involved**:
- The cell organelle primarily involved in autolysis is the lysosome. Lysosomes contain digestive enzymes that break down waste materials and cellular debris. When a lysosome bursts, these enzymes are released, leading to the breakdown of the cell's components.
