According to the endosymbiotic theory, large prokaryotic cells may have
engulfed smaller prokaryotic cells over 1.5 billion years ago. If the smaller
cells survived, the larger cells may have eventually evolved into eukaryotic
To which of the following organelles did the ingested prokaryotes most likely
A. Chloroplasts and the Golgi apparatus
B. Nuclei and mitochondria
C. Lysosomes and nuclei
D. Mitochondria and chloroplasts
A predatory or parasitic relationship
According to the endosymbiotic theory, the larger prokaryotic cell may have been predating on the smaller prokaryotic cell, before a mutual relationship developed later on. Another hypothesis is that it was probably a parasitic relationship. Over time, the phagocytosed cell survived inside the larger cell and a symbiotic relationship developed over time because it provided an evolutionary advantage.
Endosymbiotic theory is described below.
Explanation:The first piece of evidence that needed to be found to support the endosymbiotic hypothesis was whether or not mitochondria and chloroplasts have their own DNA and if this DNA is similar to bacterial DNA. This was later proven to be true for DNA, RNA, ribosomes, chlorophyll (for chloroplasts), and protein synthesis.The endosymbiotic theory is the accepted mechanism for how eukaryotic cells evolved from prokaryotic cells. It involves a cooperative relationship between two cells which allow both to survive—and eventually led to the development of all life on Earth. The hypothesis that eukaryotic cells evolved from a symbiotic association of prokaryotes—endosymbiosis—is particularly well supported by studies of mitochondria and chloroplasts, which are thought to have evolved from bacteria living in large cells.The early eukaryote cell evolved more than a billion years ago. ... The smaller prokaryotic cell or bacteria lived on in the larger prokaryote, providing it with extra energy, while the larger cell protected the small bacteria, allowing it to survive.The endosymbiosis theory explains how eukaryotic cells may have evolved from prokaryotic cells. Symbiosis is a close relationship between two different organisms.Later, a host cell engulfed a prokaryotic cell capable of photosynthesis.Endosymbiotic theory.,A theory stating that the eukaryotes evolved through a process whereby different types of free-living prokaryotes became incorporated inside larger prokaryotic cells and eventually developed into mitochondria, chloroplasts, and possibly other organelles.
i know can you plzz me with this question im sorry i didt answer your question i just need hel.
mitochondria and chloroplasts
the theory says that the bacteria which used oxygen and changed it to ATP molecules changed into mitochondria and those that used light energy to manufacture their own food changed into chloroplasts.this happened after the small prokaryotes which were bacteria were engulfed by the bigger prokaryotes of which some managed to survive and lived together through symbiosis hence the evolution to mitochondria and chloroplasts creating a eukaryotic cell.
