1. Endosymbiosis & Evidence

Key Concepts & Definitions

  • Endosymbiosis: The process where one organism engulfs another, leading to a symbiotic relationship; over time, the engulfed organism becomes a permanent part of the host cell.
  • Mitochondria & Chloroplasts: Organelles believed to have originated from free-living bacteria through endosymbiosis.
  • Membrane Layers: Double membranes surrounding mitochondria and chloroplasts, consistent with engulfing events.
  • Circular Chromosome: Genetic material in mitochondria and chloroplasts resembling bacterial DNA.
  • Division: Mitochondria and chloroplasts replicate independently via binary fission, similar to bacteria.
  • Ribosomes: Their size and structure in these organelles resemble bacterial ribosomes, supporting bacterial origin.
