Endosymbiotic Theory
Amoeba Sisters・2 minutes read
Scientific theories like the endosymbiotic theory explain scientific events with evidence, being testable and repeatedly tested. The theory details the evolution of eukaryote cells from prokaryotic cells in symbiosis, with mitochondria and chloroplasts having their DNA and dividing similarly to bacteria, supporting the theory.
Insights
- The endosymbiotic theory proposes that eukaryote cells evolved from prokaryotic cells through symbiosis, with mitochondria and chloroplasts being remnants of this process, supported by their DNA similarities and division mechanisms.
- Endosymbiosis, a key concept in biology, is not only a historical occurrence but is also observable in modern organisms like termites, showcasing the ongoing nature of symbiotic relationships in nature.
