answer 3
The answer is A: mitochondria
answer 2
Answer: The correct answer is – mitochondria. Endosymbiotic theory is an evolutionary theory that describes the origin/evolution of eukaryotic structures, chloroplasts and mitochondria in prokaryotic organisms. According to this theory, some bacteria (prokaryotic cells) were thought to live inside larger cells (i.e. in a symbiotic association). These bacteria then became part of larger cells and would have evolved into mitochondria and chloroplasts, which are now the subcellular structures of eukaryotes. So, mitochondria are the correct answer to the question.
Answer 6
Explanation: The endosymbiotic theory states that eukaryotic cells evolved through the symbiosis of unicellular prokaryotic cells such as bacteria and archaea. According to this theory, animal cells and plant cells are believed to possess mitochondria and chloroplasts respectively, through endosymbiosis.
Answer 8
The correct answer would be A) mitochondria. The endosymbiotic theory states that eukaryotic cells evolved through the symbiosis of unicellular prokaryotic cells such as bacteria and archaea. According to this theory, animal cells and plant cells are thought to possess mitochondria and chloroplasts respectively, through endosymbiosis. Mitochondria arise or are related to Rickettsiales and Proteobacteria, and chloroplasts are thought to evolve from Cyanobacteria, a nitrogen-fixing bacterium.
answer 4
The endosymbiotic theory explains that eukaryotes and prokaryotes have the same ancestor. Explains his theory based on the structure of mitochondria and chloroplasts.
Additional explanation:
The endosymbiotic theory describes that life appeared on Earth about four billion years ago. This also explains that prokaryotes, like eukaryotes, evolved from the same ancestor. There is evidence that the first eukaryote may be similar to an amoeba which engulfs its food by phagocytosis. It is claimed that the organisms (amoebas) may have ingested the prokaryotic cells that may have survived in the organism, leading to a symbiotic relationship.
Mitochondria are formed or developed when the organism swallows the microbe capable of cellular or aerobic respiration. The chloroplast was also developed from the same process. They lose the cell wall and some of the DNA because they didn’t need it. Mitochondria and chloroplasts cannot grow outside the host cell. They have their own circular structured DNA and they also have their own ribosomes.

Answer 7
The correct answer is option A which is mitochondria. Explanation: The endosymbiotic theory states that certain organelles in cells evolved from the ancient microorganism that lives in the cells and has a symbiotic relationship with the cell. According to this theory, mitochondria in cells are considered ancient aerobic bacteria because mitochondria have their own genome and produce energy.
Answer 10
The correct answer is mitochondria. In the 20th century, scientists believed that plastids and mitochondria may have originated from prokaryotes (bacteria). These would have been ingested by the cells and would live inside them (in symbiosis). This endosymbiotic theory became perfectly plausible when it was discovered (in the 1950s and 1960s) that these organelles contained their own DNA, tRNA and rRNA.
Answer 5
The endosymbiotic theory explains that eukaryotes and prokaryotes have the same ancestor. Explains his theory based on the structure of mitochondria and chloroplasts.
Additional explanation:
The endosymbiotic theory explains that life first surfaced on Earth around four billion years ago. It also states that prokaryotes and eukaryotes share the same ancestor. It is possible that the first eukaryotes were amoeba-like cells that obtained their food by phagocytosis. These organisms are said to have ingested the prokaryotic cells that may have survived in the organism. This results in the development of a symbiotic relationship.
Mitochondria form or develop when the organism ingests the microbe capable of cellular or aerobic respiration. The chloroplast grew or formed when bacteria capable of photosynthesis were ingested. They may have lost their cell wall and some of their DNA because they no longer needed it. Mitochondria and chloroplasts cannot grow outside the host cell. They have their own circular structured DNA and they also have their own ribosomes.

mitochondria of eukaryotic cells.

According to this theory, animal cells and plant cells are thought to possess mitochondria and chloroplasts respectively, through endosymbiosis.
Answer 9
The endosymbiotic theory helps to explain the origin of mitochondria and chloroplasts. Explanation: The endosymbiotic theory. He claims that organelles such as chloroplasts and mitochondria were once free-living prokaryotes that eventually lived symbiotically within larger cells, forming modern eukaryotes. Symbiogenesis, or endosymbiotic theory, is an evolutionary theory of the origin of eukaryotic cells from prokaryotic organisms, first articulated in 1905 and 1910 by Russian botanist Konstantin Mereschkowski, and advanced and supported by microbiological evidence by Lynn Margulis in 1967. supporting the endosymbiotic hypothesis was whether or not mitochondria and chloroplasts have their own DNA and whether that DNA is similar to bacterial DNA. This later proved true for DNA, RNA, ribosomes, chlorophyll (for chloroplasts), and protein synthesis.
