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, which are essential components of cellular metabolism.

Golgi Complex: The Golgi complex, also known as the Golgi apparatus, is a membrane-bound organelle that modifies, sorts, and packages proteins and lipids for transport to their final destination. It evolved as a result of endomembrane system evolution in eukaryotic cells. The Golgi complex plays a crucial role in cellular metabolism by processing and directing the transport of cellular components, thereby regulating cellular function and communication.

In conclusion, lysosomes, ribosomes, and the Golgi complex are all integral parts of cellular metabolism in eukaryotic cells. They have evolved over time to perform specific functions that allow cells to maintain homeostasis, promote survival, and support overall cellular function.

krish creations   1.)  Difference between Prokaryotic cell and Eukaryotic cell. Prokaryotic cells are primitive cells mainly found in the unicellular organisms, and they do not nucleus, instead they contain a fragment of DNA, and the organelles are not bounded by the membranes, where as the eukaryotic cells are found in all types of multicellular organisms such as plant and animal cells and they contains nucleus and membrane bound organelles. Prokaryotic cells Eukaryotic cells This cells are always unicellular Eukaryotic cells are present as either unicellular or multicellular. The size of cell is generally range from 0.2 micrometers to 2.0 micrometers in diameter Eukaryotic cells range from 10 to 100 micrometers in diameter. In prokaryotic cells, the cell wall is present and it is very complex in nature. Eukaryotic cells have cell walls very rarely, if present they have simple chemical nature. In this cells true nucleus absent, instead nucleotide is present True nucleus is present. DN
