Where Did Eukaryotic Cells Come From?
Journey to the Microcosmos・2 minutes read
Life on Earth began with prokaryotes evolving into Eukaryotes through endosymbiosis, where cells consumed other cells, leading to a mutual relationship and shared functions within organisms. Various single-celled and multicellular organisms exhibit endosymbiotic relationships with algae, providing benefits such as fuel, protection, and survival in different environments.
Insights
- Endosymbiotic Theory describes how cells engulfed other cells, like mitochondria and chloroplasts, forming a symbiotic relationship that enabled shared functions within an organism.
- Examples like Paramecium bursaria and Hydra illustrate the diverse endosymbiotic relationships in nature, emphasizing how organisms benefit from these partnerships for survival, protection, and nutritional needs.
