Examples of endosymbiosis in the following topics:
-
- Each chloroplast is surrounded by two membranes, suggestive of primary endosymbiosis.
- Not all plastids in eukaryotes derive directly from primary endosymbiosis.
- The process of secondary endosymbiosis is not unique to chlorarachniophytes.
- In fact, secondary endosymbiosis of green algae also led to euglenid protists, whereas secondary endosymbiosis of red algae led to the evolution of dinoflagellates, apicomplexans, and stramenopiles.
- Explain the relationship between endosymbiosis and plastids to the evolution of eukaryotes
-
- This major theme in the origin of eukaryotes is known as endosymbiosis, where one cell engulfs another such that the engulfed cell survives and both cells benefit .
- It is believed that over millennia these endosymbionts transferred some of their own DNA to the host cell's nucleus during the evolutionary transition from a symbiotic community to an instituted eukaryotic cell (called "serial endosymbiosis").
- A eukaryote with mitochondria engulfed a cyanobacterium in an event of serial primary endosymbiosis, creating a lineage of cells with both organelles.
- Describe the general concept of endosymbiosis and the evolution of eukaryotes
-
- Genome fusion occurs during endosymbiosis, which is the mechanism proposed as responsible for the first eukaryotic cells.
- However, the role of endosymbiosis in the development of the nucleus is more controversial.
- Within the past decade, the process of genome fusion by endosymbiosis has been proposed to be responsible for the evolution of the first eukaryotic cells .
- The double membrane would be a direct result of endosymbiosis, with the endosymbiont picking up the second membrane from the host as it was internalized.
-
- Explain the relationship between endosymbiosis and mitochondria to the evolution of eukaryotes
-
- There are two hypotheses about the origin of mitochondria: endosymbiotic and autogenous, but the most accredited theory at present is endosymbiosis.
