Abstract
1. Endosymbiosis is believed to account for mitochondria and chloroplasts.
a. Mitochondria appear to be derived from a photosynthetic purple nonsulfur bacterium that entered a eukaryotic cell about a billion (109) years ago. They provide oxidative phosphorylation to the cell.
b. Chloroplasts appear to derive from entry of a photosynthetic cyanobacterium.
2. Many proteins of both mitochondria and chloroplasts are encoded by nuclear genes, indicating that genes have moved from the organelles to the nuclear DNA.
