How are mitochondria and chloroplasts thought to have been incorporated into eukaryotic cells through the process of endosymbiosis?
Mitochondria and chloroplasts are thought to have been incorporated into eukaryotic cells through endosymbiosis, a process where a larger cell engulfed smaller prokaryotic cells. Over time, these smaller cells evolved a mutually beneficial relationship with the larger cell, eventually becoming specialized organelles within the eukaryotic cell. This theory is supported by evidence such as the similarities between these organelles and modern-day bacteria, as well as their own DNA and ability to replicate independently within the cell.

What is the evidence for the endosymbiosis hypothesis?
Evidence for the endosymbiosis hypothesis includes similarities between mitochondria/chloroplasts and bacteria (such as DNA structure and ribosomes), the ability of mitochondria/chloroplasts to replicate independently within cells, and historical precedence in the evolution of eukaryotic organisms. Additionally, the presence of a double membrane in mitochondria and chloroplasts supports the idea that these organelles were once free-living bacteria that were engulfed by an ancestral eukaryotic cell.
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 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 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.
What it call when the mitochondria in cells today are the descendants of aerobic prokaryotes that used oxygen to generate energy?
This phenomenon is known as endosymbiosis, specifically referring to the theory that mitochondria and chloroplasts originated from free-living aerobic prokaryotes that were engulfed by ancestral eukaryotic cells and established a symbiotic relationship.

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.

What two organelles have become part of the eurkaryote cell because of endosymbiosis?
The mitochondria and chloroplasts are believed to have become part of the eukaryotic cell through endosymbiosis. They were previously independent prokaryotic organisms that were engulfed by ancestral eukaryotic cells, forming a symbiotic relationship over time.
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 is another cell organelle that is thought to have originated through endosymbiosis?
Take the mitochondria as example. This organelle contains it's own circular DNA that is representative of cyanobacterial DNA. This DNA codes for some proteins also. Some mitochondrial DNA has been taken into the nuclear DNA where it's presence is rather obvious. And the mitochondria fission in reproducing themselves.
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.
Which organelle came first, mitochondria or chloroplasts?
Mitochondria came first before chloroplasts in the evolution 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.
