In a basic sense, eukaryotic cells are more complex than prokaryotic cells in their shape, function, differentiation and speciation. One theory that strongly supports eukaryotic evolution from prokaryotic cells is in the mitochondria. Mitochondria actually has its own DNA that is passed from generation to generation, The structure of the mitochondria is very similar to a basic prokaryotic cell, and some research has even indicated that the mito-DNA is actually similar to old bacterial DNA. This supports that perhaps at one point, a eukaryotic cell injested a bacterial cell, and instead of digesting it, the bacterium just stayed inside the euklaryotic cell and the two became one (this is a gross oversimplification, but the general idea remains the same).
What else can I help you with?
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.
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 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
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.

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.

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 nuclear envelope in prokaryotic or eukaryotic cells?
The nuclear envelope is found in eukaryotic cells, not in prokaryotic cells.
How are prokaryotic and eukaryotic alike and diffrent?
Prokaryotic cells have no nuclei and eukaryotic cells have a true nuclei. prokaryotic DNA is circular where eukaryotic DNA is linear.
Do prokaryotic cells contain eukaryotic organisms?
No, but eukaryotic cells contain a descendant of a prokaryotic organism.
Which type of cell is older, prokaryotic or eukaryotic?
Prokaryotic cells are older than eukaryotic cells.
What role does the endosymbiont theory play in explaining the origin of eukaryotic cells?
The endosymbiont theory explains that eukaryotic cells evolved from a symbiotic relationship between different types of prokaryotic cells. This theory suggests that mitochondria and chloroplasts, which are organelles in eukaryotic cells, were once independent prokaryotic cells that were engulfed by a larger host cell. Over time, these prokaryotic cells became integrated into the host cell and eventually evolved into the organelles we see in eukaryotic cells today. This theory helps to explain the presence of these organelles in eukaryotic cells and provides insight into the evolutionary history of these complex cells.
