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.
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.
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.
On what day did Lynn Margulis and Carl Sagan get married?
Lynn Margulis and Carl Sagan got married on April 16, 1957.
What is found in mitochondria and chloroplasts that is not found in any other organelle except the nucleus leading scientists to believe that these two organelles are actually ancient prokayotes?
Mitochondria and chloroplasts contain their own DNA, separate from the cell's nuclear DNA. This unique DNA is circular, similar to bacterial DNA, leading scientists to hypothesize that these organelles were once independent bacteria that were engulfed by a precursor to eukaryotic cells in a symbiotic relationship.
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 scientist revolutionized the way biologist think about the evolutionary history of eukaryotes?
Lynn Margulis revolutionized biologists' understanding of the evolutionary history of eukaryotes with her endosymbiotic theory, which proposed that mitochondria and chloroplasts originated from symbiotic bacteria that were engulfed by primitive eukaryotic cells.
Biologist Lynn Margulis has suggested that mitochondria and chloroplast are descendants of what kind of organisms?
bacteria
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.
According to Lynn Margulis eukaryotic cells may have evolved from?
According to Lynn Margulis, eukaryotic cells may have evolved from symbiotic relationships between different prokaryotic organisms, such as bacteria and archaea. This theory is known as endosymbiotic theory, proposing that organelles like mitochondria and chloroplasts were once independent prokaryotic cells that were engulfed by a host cell.

Where did Lynn Margulis die?
Lynn Margulis died in Amherst, Massachusetts.

When did Lynn Margulis die?
Lynn Margulis died on November 22, 2011.
What is Lynn margulis birthday?
Lynn Margulis was born on March 5, 1938.
What is Lynn Margulis's birthday?
Lynn Margulis was born on March 5, 1938.
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.
