What does the endosymbiotic theory explain the origin of eukaryotes?
Explanation: The Endosymbiotic Theory states that the mitochondria and chloroplast in eukaryotic cells were once aerobic bacteria (prokaryote) that were ingested by a large anaerobic bacteria (prokaryote). This theory explains the origin of eukaryotic cells.
What is endosymbiotic theory and explain the theory?
The endosymbiotic theory states that some of the organelles in today’s eukaryotic cells were once prokaryotic microbes. They eventually lost their cell wall and much of their DNA because they were not of benefit within the host cell. Mitochondria and chloroplasts cannot grow outside their host cell.
What is endosymbiotic theory How does this theory explain the origin of complex life forms on Earth?
Eukaryotic cells may have evolved when multiple cells joined together into one. They began to live in what we call symbiotic relationships. The theory that explains how this could have happened is called endosymbiotic theory. An endosymbiont is one organism that lives inside of another one.
How did different eukaryotic cells evolve?
According to the endosymbiotic theory, the first eukaryotic cells evolved from a symbiotic relationship between two or more prokaryotic cells. Smaller prokaryotic cells were engulfed by (or invaded) larger prokaryotic cells. They evolved into the mitochondria of eukaryotic cells.
Which of the cells shown in the figure are eukaryotic cells?
Which of the cells shown in the figure are eukaryotic cells? Explanation: All eukaryotic cells have a nucleus, endomembrane system, and mitochondria. So, of the cells shown, 5, 6, and 7 are eukaryotic cells.
Which theory explains the origin of chloroplasts and mitochondria quizlet?
The endosymbiotic theory explains how cells got their chloroplasts and mitochondria.
Why is the endosymbiotic theory important in understanding the origin of life?
Endosymbiosis is important because it is a theory that explains the origin of chloroplast and mitochondria. It is also a theory that explains how eukaryotic cells came to be.
How did the first eukaryotic cells evolve according to endosymbiotic theory?
