Indicate which statements are true. Correct all false statements by changing the underlined words.
__________ Lysosomes fuse with phagosomes to form peroxisomes.

Verified step by step guidance

1. Step 1: Understand the key cellular components involved. Lysosomes are organelles containing digestive enzymes, and phagosomes are vesicles formed around a particle engulfed by phagocytosis.
2. Step 2: Recall the process of phagosome maturation. When a phagosome fuses with a lysosome, the resulting structure is called a phagolysosome, not a peroxisome.
3. Step 3: Identify the incorrect term in the statement. The word 'peroxisomes' is incorrect because peroxisomes are distinct organelles involved in lipid metabolism and detoxification, not formed by fusion of lysosomes and phagosomes.
4. Step 4: Correct the statement by replacing 'peroxisomes' with 'phagolysosomes' to accurately describe the fusion product of lysosomes and phagosomes.
5. Step 5: Summarize the corrected statement: 'Lysosomes fuse with phagosomes to form phagolysosomes.' This reflects the proper biological process.

Key Concepts

Phagosome Formation

Phagosomes are membrane-bound vesicles formed when a cell engulfs particles, such as bacteria or debris, through phagocytosis. They serve as compartments that isolate the ingested material from the cytoplasm for further processing.

Lysosome Function and Fusion

Lysosomes are organelles containing digestive enzymes that fuse with phagosomes to form phagolysosomes, where the engulfed material is degraded. This fusion is essential for breaking down pathogens or debris inside the cell.

Peroxisomes and Their Role

Peroxisomes are distinct organelles involved in lipid metabolism and detoxification of reactive oxygen species. They are not formed by fusion of lysosomes and phagosomes, so the statement confusing peroxisomes with phagolysosomes is incorrect.
