Endosymbiosis Theory Flashcards

Flashcards based on the Labster theory page regarding the Endosymbiosis Theory and the origin of eukaryotic organelles.

Endosymbiosis Theory

The hypothesis regarding the origin of organelles within eukaryotic cells, suggesting that a larger bacteria ingested a smaller bacteria and the two began working together symbiotically.

Cyanobacteria

The specific type of bacteria that, when ingested by a larger cell, became a chloroplast and resulted in the cell becoming a plant cell.

Chloroplast and mitochondria

The major evidence for endosymbiotic theory because they act like prokaryotes, have their own DNA, and divide separately from the rest of the cell.

Binary fission

The method of division used by chloroplasts and mitochondria, which is typical of prokaryotes and supports the endosymbiotic theory.

Prokaryotes

The type of cells the theory assumes all cells on Earth once were before the development of eukaryotic organelles.

Symbiotically

The manner in which the larger and smaller bacteria worked together as a unit after ingestion, relying on each other and reproducing.
