1. Facts about the Endosymbiotic theory
1.1. Mithocondria and chloroplast have their own DNA
1.1.1. Their DNA is similar to the Prokaryotes´ DNA
1.1.2. Have also a similar size
2. Edosymbiotic theory in termites
2.1. Termites have prokaryotes that help them to digest the wood
3. How it was created the Eukaryotic cell
3.1. 1. Rise in atmospheric oxygen
3.1.1. Evolution of the oxygen-releasing pathway of photosynthesis in cyanobacteria.
3.1.2. The oxygenation of Earth’s atmosphere and waters.
3.2. 2. Ozone layer formation
3.2.1. Rise in oxygen favored organisms
3.2.2. Oxygen led to formation of the ozone layer, which allowed life to move onto land.
3.3. 3. Traits and traces
3.3.1. Traits of Early Eukaryotes
3.3.1.1. Eukaryotic cells have a nucleus enclosing their DNA and membrane-bound organelles.
3.3.1.1.1. This perform metabolic functions.
3.3.1.2. Eukaryotic cells are generally larger than prokaryotic cells.
3.3.2. Eukaryotic Traces
3.3.2.1. The oldest eukaryotic fossils date to 1.8 billion years ago
3.3.2.2. They resemble the resting stage cells
3.4. 4. Mixed Heritage
3.4.1. Eukaryotic chromosomes and DNA transcription and replication processes are similar to those of archaea.
3.4.2. It is not defined if the Eukaryote cell became from a bacterial or archaeal.
3.5. 5. Origin of the nucleus
3.5.1. The nuclueus and other internal membranes may have been a result of infolding of the plasma membrane.
3.5.2. Infoldings could have protected the cell from invasions of foreign DNA.
3.6. 6. The Endosymbiont Theory
3.6.1. One species becomes a resident inside another cell to the benefit of both.
3.6.2. Aerobic bacteria could have become the mitochondria and cyanobacteria could have become chloroplasts.
3.7. 7. Evolution of mitochondria
3.7.1. Mitochondria are similar in size to bacteria.
3.7.2. Similarity among all modern mitochondrial genomes indicates that this organelle arose only once
3.7.3. The evolution of mitochondria was an essential step toward greater eukaryotic complexity
3.8. 8. Evolution of chloroplast
3.8.1. Chloroplasts resemble cyanobacteria in metabolism and have DNA that is self -replicating.
4. Endosymbiotic theory
4.1. Explains how eukaryotes cells could evolve from prokaryotic symbiosis
4.1.1. Symbiosis means that they lived together
5. Prokaryotes and Eukaryotes
