25.5 Ever-Chаnging Life оn EаrthThe endоmembrаne system and mitоchondria are essential organelles in eukaryotic cells, but they have different origins and functions. An endomembrane system is a group of interconnected organelles that work together to modify, sort, and transport proteins and lipids within the cell. The endomembrane system is believed to be a result of infolding of the cellular membrane. Mitochondria, on the other hand, are thought to have originated from ancient bacteria that were engulfed by a primitive eukaryotic cell through the process of endosymbiosis. This process of endosymbiosis is thought to be a key event in the evolution of eukaryotic cells. The oldest fossil of eukaryotes is estimated to be 1.5 billion years. Mitochondria now function as the cell's "power plants," generating chemical energy for the cell through the process of cellular respiration.Multicellularity is a characteristic of organisms made up of more than one cell; eukaryotes. For multicellularity to work, different cells must specialize in performing different functions. Examples of cell specialization include nerve, muscle, and skin cells. In multicellular organisms, cells must be able to communicate and coordinate with each other in order to function as a cohesive whole. The evolution of the endomembrane system in eukaryotic cells enabled extensive compartmentalization. It facilitated the localization of proteins to specific cell regions, allowing for the development of multicellular organisms.
