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.
Are prokaryotic cells older than eukaryotic cells?
Yes, prokaryotic cells are generally considered to be older than eukaryotic cells in terms of evolutionary history. Fossil evidence and molecular studies suggest that prokaryotes appeared on Earth around 3.5 billion years ago, while eukaryotes evolved much later, around 1.6 billion years ago.
The endosymbiotic theory was supported by the scientist?
Lynn Margulis was the scientist who proposed and championed the endosymbiotic theory. She provided evidence to support the idea that eukaryotic cells evolved from symbiotic relationships between different prokaryotic organisms.
How would you describe the relationship between the original prokaryotic?
The original prokaryotic cells are believed to have arisen around 3.5 billion years ago and are the ancestors of all modern life. They exhibit a simple structure, lacking a nucleus and membrane-bound organelles, which distinguishes them from eukaryotic cells. The relationship between prokaryotes and eukaryotes is fundamental to understanding evolution, as eukaryotes are thought to have evolved from a symbiotic relationship between different prokaryotic species. This endosymbiotic theory suggests that certain organelles in eukaryotic cells, like mitochondria and chloroplasts, originated from absorbed prokaryotic cells.
Which organelles most likely appeared last in eukaryotic cells?
The nucleus is thought to have appeared last in eukaryotic cells. This is supported by the endosymbiotic theory, which suggests that eukaryotic cells evolved from prokaryotic cells through a series of symbiotic relationships.
Which organelle indicates that eukaryotic cells have evolved from prokaryotic cells?
Mitochondria, which are thought to have originated from a symbiotic relationship between early eukaryotic cells and aerobic bacteria, provide evidence that eukaryotic cells have evolved from prokaryotic cells. Mitochondria have their own DNA and ribosomes, similar to prokaryotic cells, and carry out cellular respiration, a process that is also similar to bacterial metabolism.
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
The presence of which organelle indicates that eukaryotic cells have evolved from prokaryotic cells?
The presence of mitochondria in eukaryotic cells indicates that they have evolved from prokaryotic cells. Mitochondria have their own DNA and ribosomes, similar to prokaryotic cells, and are believed to have originated from a symbiotic relationship between an ancestral prokaryotic cell and an archaeon.
What is the difference between something eukaryotic and something prokaryotic?
There are quite a few differences between eukaryotic and prokaryotic cells. Prokaryotic cells do not have a nucleus, while eukaryotic cells do. Prokaryotic cells are not found in humans while eukaryotic cells are. Prokaryotic cells are primitive while eukaryotic cells are much more evolved.
What is cellular organization?
It basically means all cells are divided into two types: prokaryotic cells and eukaryotic cells. Prokaryotic cells evolved 3.5 billion years ago and have a nucleus. Examples of a Prokaryotic cell include protista, fungi, plants and animals. Eukaryotic cells evolved 1.5 billion years ago and do not have a nucleus. An example of a Eukaryotic cell is bacteria.
What was the theory developed around the idea some eukaryotic organelles evolved from prokaryotic organisms?
endosymbiont
Mitochondria prokaryotic or eukaryotic?
Mitochondria are considered to be eukaryotic organelles. They have their own DNA and ribosomes, and are thought to have evolved from engulfed prokaryotic cells in a symbiotic relationship with 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 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.
Which is used as evidence for the idea that multicellular organisms evolved from prokaryotes?
Mitochondria and chloroplasts have their own DNA
Are prokaryotic cells older than eukaryotic cells?
Yes, prokaryotic cells are generally considered to be older than eukaryotic cells in terms of evolutionary history. Fossil evidence and molecular studies suggest that prokaryotes appeared on Earth around 3.5 billion years ago, while eukaryotes evolved much later, around 1.6 billion years ago.
