What statement best supports the theory that eukaryotic cells evolved through endosymbiosis?
The presence of organelles like mitochondria and chloroplasts with their own DNA and membrane structure closely resembling that of bacteria supports the theory of endosymbiosis, where a prokaryotic cell engulfed another prokaryotic cell and formed a symbiotic relationship over time. Additionally, the fact that these organelles replicate independently of the host cell and have similarities to certain types of bacteria further strengthens the endosymbiotic theory of eukaryotic cell evolution.

What is the role of endosymbiosis in the evolution of eukaryotic cells?
Endosymbiosis played a crucial role in the evolution of eukaryotic cells by allowing for the incorporation of symbiotic bacteria that eventually evolved into organelles like mitochondria and chloroplasts. This process helped eukaryotic cells gain new functions and capabilities, leading to their complexity and diversity.
How does endosymbiosis play a role in the evolution of prokaryotes to eukaryoteAsk us anything?
Endosymbiosis is a theory that explains how prokaryotic cells evolved into eukaryotic cells by forming symbiotic relationships with other prokaryotic cells. This process led to the development of organelles such as mitochondria and chloroplasts within eukaryotic cells. Endosymbiosis helped eukaryotic cells gain new functions and capabilities, contributing to their complexity and diversity.
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.
Is the evolution of the prokaryote before a eukaryote cell?
Yes, prokaryotic cells evolved before eukaryotic cells. Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have both. It is believed that eukaryotic cells evolved from prokaryotic cells through a process called endosymbiosis.
Is the following true or false The ancestor of all eukaryotic cells evolved about 2 billion years ago?
True. The ancestor of all eukaryotic cells is thought to have evolved approximately 2 billion years ago through a process of endosymbiosis, where prokaryotic cells engulfed other prokaryotic cells, leading to the formation of more complex eukaryotic cells.

What kind of bacteria evolved into the eukaryote chloroplast?
It is believed that cyanobacteria, also known as blue-green algae, evolved into the eukaryote chloroplast through a process called endosymbiosis. This process involved a cyanobacterium being engulfed by a eukaryotic cell and forming a symbiotic relationship, eventually leading to the development of the chloroplast organelle found in plant and algal 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 does the endosymbiosis theory propose?
The endosymbiosis theory proposes that eukaryotic cells evolved from symbiotic relationships between different prokaryotic organisms. It suggests that organelles such as mitochondria and chloroplasts were once independent prokaryotes that were engulfed by a host cell, eventually forming a mutually beneficial relationship.
How do scientist think the first protists evolved?
endosymbiosis.

What are the evolutionary relationships between prokaryotic and eukaryotic cells?
Mitochondria and chloroplasts have prokaryote-like features. For example, although most of the DNA in eukaryotic cells resides in the nucleus, both mitochondria and chloroplasts have DNA molecules in their inner compartments. Mitochondrial and chloroplastic ribosomes are similar to the ribosomes of prokaryotes. The endosymbiont theory proposes that eukaryotic organisms evolved from prokaryotic ancestors; this idea supports the notion that organelles evolved from prokaryotic organisms that originally lived inside larger cells, eventually losing the ability to function as autonomous organisms
When was the endosymbiotic theory proposed?
The endosymbiotic theory was proposed in the 1960s by Lynn Margulis to explain the origin of eukaryotic cells. It suggests that eukaryotic cells evolved through a mutually beneficial relationship between primitive prokaryotic cells.
What was the ultimate origin of all plastids?
The ultimate origin of all plastids is believed to be cyanobacteria through a process called primary endosymbiosis. This involved a eukaryotic cell engulfing a cyanobacterium, which eventually evolved into plastids such as chloroplasts in plants.
What are the two theories of evolution in a eukaryotic cell?
The two theories of evolution in a eukaryotic cell are endosymbiotic theory and gene duplication. Endosymbiotic theory suggests that eukaryotic cells evolved from a symbiotic relationship between different prokaryotic organisms. Gene duplication theory suggests that gene duplication events have played a significant role in the evolutionary development of new functions and complexity in eukaryotic cells.
