The correct answer is option 1, lysosomes. Lysosomes are known as "suicide bags" of a cell because they contain enzymes that can break down cellular waste and debris. They act as the recycling centers of the cell, digesting and recycling old, damaged organelles, proteins, and other cellular materials.

Let`s evaluate the other options to understand why they are not the correct answer:

Option 2, plastids, are not typically referred to as "suicide bags" of a cell. Plastids are a group of organelles found in plant cells, including chloroplasts that carry out photosynthesis.

Option 3, the endoplasmic reticulum (ER), is a complex network of membranes involved in protein synthesis, lipid metabolism, and calcium ion storage. It is not known as "suicide bags" of a cell.

Option 4, mitochondria, are often referred to as the "powerhouse" of the cell because they produce energy through cellular respiration. They are involved in generating ATP, the main energy currency of the cell, but they are not known as "suicide bags."

In conclusion, lysosomes are correctly known as the "suicide bags" of a cell due to their role in breaking
