What theory was developed around the idea that some eukaryotic organelles evolved from proyarotic organisms?
The endosymbiotic theory proposes that eukaryotic organelles, such as mitochondria and chloroplasts, originated from engulfed prokaryotic cells that developed a symbiotic relationship within the host cell. This theory suggests that these organelles were once free-living bacteria that were engulfed by early eukaryotic cells and eventually evolved into essential components of eukaryotic cells.
What did Lynn Margulis account for the presence of DNA in Chromatin and Chromosomes?
Lynn Margulis proposed the endosymbiotic theory to explain the presence of DNA in chromatin and chromosomes. This theory suggests that eukaryotic cells, which contain DNA in their mitochondria and chloroplasts, arose from symbiotic relationships between ancient prokaryotic cells.
What evolved from prokaryotes?
Eukaryotic cells evolved from prokaryotes.
What did Lynn Margulis discover?
Lynn Margulis is well-known for proposing the endosymbiotic theory, which suggests that eukaryotic cells evolved through a symbiotic relationship between different types of prokaryotic cells. This theory provides an explanation for the origin of organelles such as mitochondria and chloroplasts.
Which organelle indicates that eukaryotic cells have evolved from prokaryotic cells?
Mitochondria, which are thought to have originated from a symbiotic relationship between early eukaryotic cells and aerobic bacteria, provide evidence that eukaryotic cells have evolved from prokaryotic cells. Mitochondria have their own DNA and ribosomes, similar to prokaryotic cells, and carry out cellular respiration, a process that is also similar to bacterial metabolism.
When was the endosymbiotic theory proposed?
The endosymbiotic theory was proposed in the 1960s by Lynn Margulis to explain the origin of eukaryotic cells. It suggests that eukaryotic cells evolved through a mutually beneficial relationship between primitive prokaryotic cells.
Describe margulis' theory about the evolution of protists?
Lynn Margulis proposed the endosymbiotic theory, suggesting that eukaryotic cells originated from the incorporation of prokaryotic cells through symbiosis. She specifically highlighted the role of bacterial ancestors, such as mitochondria and chloroplasts, in the evolution of protists. According to Margulis, these symbiotic relationships contributed to the complexity and diversification of protists.

The endosymbiotic theory was supported by the scientist?
Lynn Margulis was the scientist who proposed and championed the endosymbiotic theory. She provided evidence to support the idea that eukaryotic cells evolved from symbiotic relationships between different prokaryotic organisms.
What evolved from prokaryotes?
Eukaryotic cells evolved from prokaryotes.

What is biologists Lynn margulis's hypothesis about where the first protists came from?
Lynn Margulis proposed the endosymbiotic theory, suggesting that organelles such as mitochondria and chloroplasts in eukaryotic cells evolved from symbiotic relationships between different types of prokaryotic cells. This hypothesis explains the origins of protists and other eukaryotic organisms through the merging of different cell types rather than gradual evolution from a single organism.
Are chloroplasts found in plant cells why?
This is an accident of how the first eukaryotic plant cells evolved to be different from other eukaryotic cells billions of years ago. It is what defines eukaryotic plants.
Which organelle indicates that eukaryotic cells have evolved from prokaryotic cells?
Mitochondria, which are thought to have originated from a symbiotic relationship between early eukaryotic cells and aerobic bacteria, provide evidence that eukaryotic cells have evolved from prokaryotic cells. Mitochondria have their own DNA and ribosomes, similar to prokaryotic cells, and carry out cellular respiration, a process that is also similar to bacterial metabolism.
Why are the chloroplasts found in plant cells only?
This is an accident of how the first eukaryotic plant cells evolved to be different from other eukaryotic cells billions of years ago. It is what defines eukaryotic plants.
American biologist who provided evidence for the endosymbiotic theory which explains the origin of chloroplasts and mitochondra?
Lynn Margulis is the American biologist known for her work on the endosymbiotic theory. She proposed that chloroplasts and mitochondria evolved from ancient prokaryotic cells that were engulfed by a host cell. Her research provided evidence supporting the idea that these organelles have their own DNA and replicate independently within eukaryotic cells.
