Discuss evolutionary aspects of lysosomes, ribosomes, and Golgi complex in the eukaryotic cells          and discuss its role in cellular metabolism. answer : Lysosomes: Lysosomes are membrane-bound organelles in eukaryotic cells that contain hydrolytic enzymes. They evolved as a result of endosymbiosis, where a free-living bacterium was engulfed by a primitive eukaryotic cell, and over time, the bacterium evolved into a lysosome. Lysosomes play a key role in cellular metabolism by breaking down and recycling cellular waste, including cellular debris, and worn-out organelles. This process helps maintain cellular homeostasis and promotes cellular survival. Ribosomes: Ribosomes are cellular structures that are found in both prokaryotic and eukaryotic cells. They evolved from an ancestral precursor and have been preserved throughout evolution due to their important role in protein synthesis. In eukaryotic cells, ribosomes are involved in the translation of messenger RNA into proteins, whi
