Study Notes

Endosymbiotic Theory

  • The Endosymbiotic Theory was proposed by scientist Lynn Margulis.
  • The main idea of the Endosymbiotic Theory is that the main organelles of the eukaryotic cell originated from ancient bacteria that were engulfed by the cell and formed a symbiotic relationship.

Origin of Eukaryotic Cell Organelles

  • The main organelles of the eukaryotic cell, such as mitochondria and chloroplasts, were originally ancient bacteria that were engulfed by the cell.

Response to the Endosymbiotic Theory

  • The initial response to Lynn Margulis' theory was met with skepticism and resistance.

Evidence Supporting the Endosymbiotic Theory

  • Lynn Margulis studied the similarities between bacteria and eukaryotic cell organelles to support her theory.

Viral Replication

  • The stage of viral replication that involves the release of new viral particles from the host cell is called lysis.
  • The process of a virus entering a host cell is called penetration.
  • The stage of viral replication that involves the virus attaching to the surface of the host cell is called adsorption.
