The endosymbiotic theory states that primitive cells engulfed other primitive cells and in this way complex cells were formed. This theory suggests that the ability of cells to form organelles like the mitochondria and chloroplasts is due to the engulfment of primitive cells. The engulfed primitive cell then formed a symbiotic relationship with the host cell providing energy to the host cell while receiving protection and nutrition. This symbiotic relationship eventually led to the formation of cells with organelles which are known as eukaryotic cells.
If the endosymbiotic theory is true cells would become more complex with the ability to store more energy and develop more advanced structures. This would enable them to perform more complex functions and become more efficient. For example cells with mitochondria and chloroplasts would be able to produce more energy-rich molecules such as ATP which would give them the ability to perform more tasks. Additionally the presence of membrane-bound organelles would allow for compartmentalization of the cell which would enable the cell to perform different functions simultaneously.
In addition to the development of organelles the presence of a eukaryotic cell would also allow for the formation of specialized cell structures such as cilia and flagella. These structures would enable the cell to move further increasing its ability to survive and reproduce. Furthermore the presence of a nucleus would allow for the development of genetic material which would enable the cell to make copies of itself and pass on its genetic information to its offspring.
What else can I help you with?
What statement fails to support the endosymbiotic theory?
A statement that fails to support the endosymbiotic theory would be one that asserts that all eukaryotic organelles were independently formed within the cells, without any symbiotic relationship with prokaryotic cells. This contradicts the evidence and principles of the endosymbiotic theory, which suggests that organelles like mitochondria and chloroplasts originated from ancient symbiotic relationships between prokaryotic cells and ancestral eukaryotic cells.
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 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.
Which discovery supported the endosymbiotic theory?
The discovery of mitochondria and chloroplasts having their own DNA, ribosomes, and double membrane structure supports the endosymbiotic theory, which proposes that these organelles were once free-living prokaryotes that were engulfed by ancestral eukaryotic cells. This evidence suggests that they evolved from symbiotic relationships between different cell types.
What process is thought to be involved in the genesis of eukaryotes from prokaryotes?
It is almost certain that DNA-bearing organelles like the mitochondria and the chloroplasts are what remains of ancient symbiotic oxygen-breathing proteobacteria and cyanobacteria, respectively, where the rest of the cell seems to be derived from an ancestral archaean prokaryote cell - a theory termed the endosymbiotic theory.
What are the 3 main steps of the endosymbiotic theory?
The endosymbiotic theory was first articulated by Russian botanist Konstantin Mereschkowski in 1910. It states that several key organelles of eukaryotes began as symbioses between two or more single-celled organisms.
What statement fails to support the endosymbiotic theory?
A statement that fails to support the endosymbiotic theory would be one that asserts that all eukaryotic organelles were independently formed within the cells, without any symbiotic relationship with prokaryotic cells. This contradicts the evidence and principles of the endosymbiotic theory, which suggests that organelles like mitochondria and chloroplasts originated from ancient symbiotic relationships between prokaryotic cells and ancestral eukaryotic cells.
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 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 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 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.
Is a mitochondria a bacterial Cell?
Yes, according to the The endosymbiotic theory:The endosymbiotic theory concerns the mitochondria, plastids (e.g. chloroplasts), and possibly other organelles of eukaryotic Cells. According to this theory, certain organelles originated as free-living bacteria that were taken inside another Cell as endosymbionts. Mitochondria developed from proteobacteria (in particular, Rickettsiales or close relatives) and chloroplasts from cyanobacteria.
Endosymbiotic theory explains the formation of organelles surrounded by how many membranes?
Endosymbiotic theory explains the formation of organelles surrounded by two membranes. This theory suggests that eukaryotic organelles such as mitochondria and chloroplasts originated from symbiotic prokaryotic cells that were engulfed by a host cell, leading to a mutually beneficial relationship.
Is endosymbiotic theory true?
Yes, the endosymbiotic theory is widely accepted as a valid explanation for the origin of eukaryotic cells. It proposes that mitochondria and chloroplasts were once free-living prokaryotic organisms that were engulfed by a larger host cell, forming a symbiotic relationship. Over time, these engulfed organisms evolved into organelles within the host cell.
What concept explains the presence of mitochondria in cell?
The concept that explains the presence of mitochondria in cells is the endosymbiotic theory. Mitochondria in cells derived from the extra embryonic membranes.
Which discovery supported the endosymbiotic theory?
The discovery of mitochondria and chloroplasts having their own DNA, ribosomes, and double membrane structure supports the endosymbiotic theory, which proposes that these organelles were once free-living prokaryotes that were engulfed by ancestral eukaryotic cells. This evidence suggests that they evolved from symbiotic relationships between different cell types.
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.
