What role does the endosymbiont theory play in explaining the origin of eukaryotic cells?
The endosymbiont theory explains that eukaryotic cells evolved from a symbiotic relationship between different types of prokaryotic cells. This theory suggests that mitochondria and chloroplasts, which are organelles in eukaryotic cells, were once independent prokaryotic cells that were engulfed by a larger host cell. Over time, these prokaryotic cells became integrated into the host cell and eventually evolved into the organelles we see in eukaryotic cells today. This theory helps to explain the presence of these organelles in eukaryotic cells and provides insight into the evolutionary history of these complex cells.
The endosymbiotic theory provides the explanation for the origin of what?
The endosymbiotic theory explains the origin of eukaryotic cells by proposing that mitochondria and chloroplasts were once free-living prokaryotic organisms that were engulfed by primitive eukaryotic cells. Over time, a symbiotic relationship developed, leading to the integration of these organelles into eukaryotic cells.
What is the main characteristic that distinguishes prokaryotes and eukaryotes?
Prokaryotic cells have genetic material that is not contained in a nucleus; Eukaryotic cells contain a nucleus in which their genetic material is separated from the rest of the cell. Also, keep in mind that eukaryotic cells are known to have a nucleus while prokaryotic cells do not.
Eukaryotic cells acquired mitochondria and chloroplasts by?
engulfing prokaryotic cells through a process called endosymbiosis. Over time, these prokaryotic cells formed a mutualistic relationship with the host cell, eventually evolving into the mitochondria and chloroplasts found in eukaryotic cells today.
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.

Is the oldest known fossils prokaryotic or eukaryotic?
The oldest known fossils are prokaryotic. These fossils, dating back over 3.5 billion years, are believed to be ancient bacteria and archaea. Eukaryotic cells are thought to have evolved later.

From where did eukaryotes evolve?
Unlike their cousin cells, the Prokaryotic cells, Eukaryotic cells bear a nucleus. They are found in animals, plants, fungi and protists. The presence of a nucleus gives these organisms their name, which comes from the Greek ευ (eu), meaning "good/true," and κάρυον (karyon), which means "kernal." Does that help at all?
Eukaryotic cells acquired mitochondria and chloroplasts by?
engulfing prokaryotic cells through a process called endosymbiosis. Over time, these prokaryotic cells formed a mutualistic relationship with the host cell, eventually evolving into the mitochondria and chloroplasts found in eukaryotic cells today.
What is the evolutionary hypothesis that some organelles are remnants of prokaryotic cells?
The endosymbiotic theory proposes that some organelles, such as mitochondria and chloroplasts, were once free-living prokaryotic cells that were engulfed by a host cell through endocytosis. Over time, these prokaryotic cells formed a symbiotic relationship with the host cell, eventually evolving into permanent organelles within the eukaryotic cell.
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.
What describes a prokaryotic cell?
Prokaryotic cells have ribosomes, plasmids, cytoplasm, plasma membrane, cell wall, and a nucleoid. They do not have a membrane-bound nucleus like Eukaryotes do.
How did mitochondria and chloroplasts most likely arise in eukaryotic cells?
Mitochondria and chloroplasts most likely arose in eukaryotic cells through a process called endosymbiosis, where a host cell engulfed a prokaryotic cell. Over time, the prokaryotic cell evolved to become an organelle within the host cell, forming a symbiotic relationship. This theory is supported by the similarities between mitochondria and chloroplasts and modern-day bacteria.
How did mitochondria and chloroplasts develop within eukaryotic cells?
Mitochondria and chloroplasts are believed to have developed within eukaryotic cells through a process called endosymbiosis. This theory suggests that these organelles were once independent prokaryotic organisms that were engulfed by a larger host cell. Over time, a mutually beneficial relationship developed between the organelles and the host cell, leading to their integration and specialization within eukaryotic cells.
Is a water strider a prokayotic or eukaryotic?
A water strider is in the kingdom Animalia in the phylum Arthropoda, class Insecta. As a common rule, if a living system is classified under Animalia in the five kingdom system it is a eukaryote. Prokaryotic organisms pertain to bacteria and archeal life forms. An over-simplified means of cellular identification is Eukaryotes have cellular organelles, while prokaryotes do not.
