How mitochondria or chloroplasts evolved?
Endosymbiotic theory describes the evolution of mitochondria and chloroplast.According to it,photosynthetic bacteria and aerobic bacteria engulfed by a eukaryotic cell turned into chloroplast and mitochondria.
Which of these cellular organelles have their own DNA?
Mitochondria and chloroplasts have their own DNA. Mitochondria DNA is circular, similar to bacterial DNA, and is inherited maternally. Chloroplasts also have circular DNA and are thought to have originated from endosymbiotic relationships with ancient prokaryotes.
Many scientists think that early aerobic prokaryotes invaded larger cells and eventually gave rise to?
the eukaryotic cells through an endosymbiotic relationship. This theory is called the endosymbiotic theory and proposes that mitochondria and chloroplasts in eukaryotic cells were once free-living bacteria that were engulfed by a larger host cell and formed a symbiotic relationship.
What does the endosymbiotic theory purpose?
concerns the origins of mitochondria and plastids (e.g. chloroplasts), which are organelles of eukaryotic cells. According to this theory, these organelles originated as separate prokaryotic organisms which were taken inside the cell as endosymbionts. Mitochondria developed from proteobacteria (in particular, Rickettsiales or close relatives) and chloroplasts from cyanobacteria. concerns the origins of mitochondria and plastids (e.g. chloroplasts), which are organelles of eukaryotic cells.

What acts like chloroplast?
Mitochondria act like chloroplasts in plants as they both generate energy for the cell through cellular respiration and photosynthesis, respectively. Both organelles have their own DNA and ribosomes, supporting the endosymbiotic theory that mitochondria and chloroplasts were once free-living prokaryotic cells that were engulfed by a primitive eukaryotic cell.
What is the endosymbiotic theory?
The Endosymbiotic Theory is a theory about how mitochondria and chloroplasts formed. The theory suggests that both the mitochondria and chloroplasts were once prokaryotic cells that were ingested but not digested by eukaryotic cells. This would explain why both have their own DNA.
How mitochondria or chloroplasts evolved?
Endosymbiotic theory describes the evolution of mitochondria and chloroplast.According to it,photosynthetic bacteria and aerobic bacteria engulfed by a eukaryotic cell turned into chloroplast and mitochondria.
What two organelles are derived from symbiotic bacteria?
Chloroplasts and mitochondria. It is believed they were engulfed by the cells because of the dual membrane present on both. Both are believed to have originated from an endosymbiotic bacteria. Mitochondria's inner matrices contain DNA, and they have many features similar to those of bacteria. Chloroplasts are believed to have come from an endosymbiotic cyanobacteria.
Which of these cellular organelles have their own DNA?
Mitochondria and chloroplasts have their own DNA. Mitochondria DNA is circular, similar to bacterial DNA, and is inherited maternally. Chloroplasts also have circular DNA and are thought to have originated from endosymbiotic relationships with ancient prokaryotes.
What organelles that have a double membrane?
Nucleus Mitochondria
Is a mitochondria a bacterial Cell?
Yes, according to the The endosymbiotic theory:The endosymbiotic theory concerns the mitochondria, plastids (e.g. chloroplasts), and possibly other organelles of eukaryotic Cells. According to this theory, certain organelles originated as free-living bacteria that were taken inside another Cell as endosymbionts. Mitochondria developed from proteobacteria (in particular, Rickettsiales or close relatives) and chloroplasts from cyanobacteria.
What organelle does the endosymbiotic theory suggest evolved from the symbiotic relationships between prokaryotic cells?
The endosymbiotic theory suggests that mitochondria and chloroplasts evolved from symbiotic relationships between prokaryotic cells. More specifically, mitochondria are proposed to have originated from aerobic bacteria, while chloroplasts are thought to have originated from photosynthetic bacteria.
What is the evidence for endosymbiotic hypothesis?
The endosymbiotic hypothesis postulates that an early eukaryotic cells lacking mitochondria and chloroplasts phagocytosed early aerobic prokaryotes and photosynthetic prokaryotes and rather than
What theory states that mitochondria and chloroplasts are derived from free-living prokaryotic cells?
The endosymbiotic theory proposes that mitochondria and chloroplasts were once free-living prokaryotic cells that were engulfed by a primitive eukaryotic cell through symbiosis. Over time, these engulfed cells evolved into organelles within the host cell, leading to the development of modern eukaryotic cells.
How are chloroplasts and mitochondria similar to bacteria?
Chloroplasts and mitochondria have their own DNA and ribosomes, similar to bacteria. They also reproduce independently within the cell through a process resembling binary fission, just like bacteria. Additionally, both organelles are thought to have originated from endosymbiotic relationships with ancient bacterial cells.
What statement fails to support the endosymbiotic theory?
A statement that fails to support the endosymbiotic theory would be one that asserts that all eukaryotic organelles were independently formed within the cells, without any symbiotic relationship with prokaryotic cells. This contradicts the evidence and principles of the endosymbiotic theory, which suggests that organelles like mitochondria and chloroplasts originated from ancient symbiotic relationships between prokaryotic cells and ancestral eukaryotic cells.
Two organelles that are believed to be descendants of unicellular bacteria are?
Two organelles that are believed to be descendants of unicellular bacteria are mitochondria and chloroplasts. The endosymbiotic theory suggests that these organelles were once free-living bacteria that were engulfed by ancestral eukaryotic cells and formed a symbiotic relationship.
