Which organelles evolved from small prokaryotes that established residence within other larger prokaryotes?
Mitochondria and chloroplasts evolved from small prokaryotes that were engulfed by larger prokaryotic cells through endosymbiosis. Over time, these small prokaryotes established a symbiotic relationship with their host cells, eventually evolving into specialized organelles that are essential for cellular respiration and photosynthesis, respectively.
What are mitochondria the descendants of?
Mitochondria are thought to be descendants of ancient bacteria that were engulfed by early eukaryotic cells through a process called endosymbiosis. Over time, this symbiotic relationship evolved into the mitochondria we see in cells today.
What is the origin of chloroplasts?
Chloroplasts originated from a process called endosymbiosis, where a eukaryotic cell engulfed a photosynthetic cyanobacteria. Over time, a symbiotic relationship developed where the cyanobacteria became integrated into the cell and evolved into what we now recognize as chloroplasts. This event is believed to have occurred around 1.5 billion years ago, contributing to the evolution of photosynthetic organisms.
How mitochondria or chloroplasts evolved?
Endosymbiotic theory describes the evolution of mitochondria and chloroplast.According to it,photosynthetic bacteria and aerobic bacteria engulfed by a eukaryotic cell turned into chloroplast and mitochondria.
What must be true if prokaryotes evolved into eukaryotes by absorbing?
If prokaryotes evolved into eukaryotes by absorbing other prokaryotic cells, it must be true that the engulfed cells retained some functional capacity, allowing them to contribute to the metabolic processes of the host cell. This endosymbiotic theory suggests that these absorbed cells eventually became organelles, such as mitochondria and chloroplasts, through a symbiotic relationship. Additionally, genetic material from the engulfed cells would need to be integrated into the host's genome or maintained separately, facilitating cooperation and communication between the host and its symbionts.

What did engulfed aerobic prokaryotes become?
Engulfed aerobic prokaryotes evolved into mitochondria through a process known as endosymbiosis. This symbiotic relationship allowed the host cell to utilize the prokaryotes' ability to perform aerobic respiration, leading to increased energy production. Over time, these engulfed prokaryotes lost their independence and became integral components of eukaryotic cells, contributing to the complexity of life forms.
What is thought to be engulfed by prokaryotes eventually leading to the development of animal cells?
It is thought that mitochondria were engulfed by prokaryotes, which eventually developed into animal cells. This event led to the creation of a symbiotic relationship between the host cell and the engulfed mitochondria, giving rise to complex eukaryotic cells.

Did the evolution of prokaryotes preceed the evolution of eukaryotes?
Yes, prokaryotes are believed to have evolved before eukaryotes. Eukaryotes likely evolved through a process of endosymbiosis, where prokaryotic cells engulfed other prokaryotic cells to form a symbiotic relationship, leading to the development of cellular organelles.
Is used as evidence for the idea that multicellular organisms evolved from prokaryotes?
Mitochondria and chloroplasts have their own DNA.
What must be true if prokaryotes evolved into eukaryotes by absorbing?
If prokaryotes evolved into eukaryotes by absorbing other prokaryotic cells, it must be true that the engulfed cells retained some functional capacity, allowing them to contribute to the metabolic processes of the host cell. This endosymbiotic theory suggests that these absorbed cells eventually became organelles, such as mitochondria and chloroplasts, through a symbiotic relationship. Additionally, genetic material from the engulfed cells would need to be integrated into the host's genome or maintained separately, facilitating cooperation and communication between the host and its symbionts.
What is the Capture hypothesis?
The Capture hypothesis proposes that organelles such as mitochondria and chloroplasts were derived from free-living prokaryotes that were engulfed by a host cell but not digested. Over time, these engulfed prokaryotes established a symbiotic relationship with the host cell, eventually becoming permanent residents within the cell. This theory is supported by the presence of prokaryotic-like features in mitochondria and chloroplasts, as well as their own genetic material.
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.
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.
