Prokaryotes lack membrane-bound organelles.
Lysosomes are membrane-bound organelles found in eukaryotic cells that play a vital role in maintaining the health and functionality of cells. They are involved in the process of cellular digestion and waste removal.
The main function of lysosomes is to break down worn-out cell parts, such as organelles, proteins, and other cellular debris that are no longer needed or functioning properly. This process is called autophagy, and it allows the cell to recycle and reuse valuable resources. By breaking down and recycling these components, lysosomes help maintain the overall health and efficiency of the cell.
Additionally, lysosomes are responsible for destroying and digesting invading pathogens, such as bacteria, viruses, and foreign particles that may enter the cell. This function is crucial for the immune response and defense against infections.
In summary, lysosomes are important for maintaining the health of cells by removing waste, recycling materials, and defending against intruders.
