What is the endosymbiotic theory and what organelles came from it?
Introduction. Endosymbiotic theory posits that plastids and mitochondria were once free-living prokaryotes and became organelles of eukaryotic cells. The theory started with plastids [1] and was further developed for mitochondria [2]. It was rejected by cell biologists in the 1920s and revived in the 1960s [3].
Which two organelles are most closely associated with the endosymbiotic theory?
The endosymbiotic origin of mitochondria and chloroplasts is widely believed because of the many similarities between prokaryotes and these organelles: 1. Mitochondria and chloroplasts are similar in size and shape to prokaryotes. 2.
Where did organelles come from endosymbiotic theory?
Endosymbiotic theory goes back over 100 years. It explains the similarity of chloroplasts and mitochondria to free-living prokaryotes by suggesting that the organelles arose from prokaryotes through (endo)symbiosis.
What are 3 pieces of evidence for the endosymbiotic theory?
Numerous lines of evidence exist, including that mitochondria and chloroplasts have their own circular DNA (prokaryotes also have circular DNA), mitochondria and chloroplasts have a double membrane (the inner membrane would have initially been the ingested prokaryote’s single membrane, and the outer membrane initially …
What are the 4 organelles all cells have in common?
All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. The plasma membrane, or cell membrane, is the phospholipid layer that surrounds the cell and protects it from the outside environment. Ribosomes are the non-membrane bound organelles where proteins are made, a process called protein synthesis.
What two organelles were created as a result of the theory of endosymbiosis?
According to the Endosymbiotic Theory, endosymbiosis became the means by which organelles such as mitochondria and chloroplasts within eukaryotic cells came about.
Which of the following organelles support the endosymbiotic theory choose all that apply?
Which evidence supports the endosymbiotic theory? Select all that apply. Mitochondria and chloroplasts have a separate, simpler DNA from the nucleus DNA of a eukaryotic cell. These organelles’ DNA resembles the DNA of prokaryotic cells.
