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 did Dr. Lynn Margulis suggest about mitochondria and chloroplasts?
They were cells before and then they came together with a cell and then they became mutually dependent.
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.
What did virchowschleidan and schwann each contribute to the cell theory?
The name of the theory that Schleiden and Schwann developed is the cell theory.
What 2 dna-containing organelles support Margulis theory of endosymbiosis?
The two DNA-containing organelles that support Margulis' theory of endosymbiosis are mitochondria and chloroplasts. These organelles contain their own DNA, which is separate from the nuclear DNA of the cell, and share some similarities with bacteria, indicating that they were once free-living prokaryotic organisms that were engulfed by a host cell and formed a symbiotic relationship.
How did Lynn margulis contribute to the cell theory?
she didn't
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 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 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.
What did Dr. Lynn Margulis suggest about mitochondria and chloroplasts?
They were cells before and then they came together with a cell and then they became mutually dependent.
Why there is a DNA in the mitochondria?
The consensus is that the mitochondria was once a free living single cell prokaryote that was engulfed and perhaps enslaved, perhaps joined as a symbiont with a burgeoning eukaryote cell type. Thus, this organelle kept some of it's own DNA. Google the endosymbiotic theory by Lynn Margulis.

What did virchow contribute to cell theory?
He said that cells can reproduce cell
What did Rudolf Virchow do to contribute to the cell theory?
nothing
