This is the endosymbiotic theory.
Viruses are technically not alive, and so are not classified as cells. Only cells are classified as prokaryotic or eukaryotic. For cells, prokaryotic means it has no nucleus while eukaryotic means it has a nucleus.
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.
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.
The nuclear envelope is found in eukaryotic cells, not in prokaryotic cells.
Prokaryotic cells have no nuclei and eukaryotic cells have a true nuclei. prokaryotic DNA is circular where eukaryotic DNA is linear.
Eukaryotic cells are generally larger than prokaryotic cells. Eukaryotic cells have a more complex structure with membrane-bound organelles like the nucleus, while prokaryotic cells lack these organelles. This allows eukaryotic cells to grow larger in size.
No, but eukaryotic cells contain a descendant of a prokaryotic organism.
Prokaryotic cells are older than eukaryotic cells.
Prokaryotic cells do not have a nucleus or membrane-bound organelles, while eukaryotic cells have a nucleus and membrane-bound organelles. Prokaryotic cells are usually smaller and simpler in structure compared to eukaryotic cells.
Eukaryotic cells contain organelles that are enclosed in membranes
Both eukaryotic cells and prokaryotic cells have a plasma membrane.
The plasma membrane of cells is found in both prokaryotic and eukaryotic cells.
