Can you distinguish the prokaryotic organisms from the eukaryotic organisms explain?
Prokaryotic organisms, such as bacteria and archaea, are unicellular and lack a true nucleus and membrane-bound organelles, with their genetic material organized in a single circular chromosome. In contrast, eukaryotic organisms, which include animals, plants, fungi, and protists, are typically multicellular (though some are unicellular) and possess a defined nucleus that houses their linear chromosomes, along with various membrane-bound organelles. This fundamental difference in cellular organization is a key characteristic that distinguishes the two groups.

The endosymbiotic theory has been developed to explain the emergence of?
The endosymbiotic theory has been developed to explain the emergence of eukaryotic cells, proposing that certain organelles within eukaryotic cells were once free-living prokaryotic organisms that were engulfed by a larger host cell and formed a symbiotic relationship. This theory is supported by evidence such as the mitochondria and chloroplasts having their own DNA and ribosomes, similar to bacteria.
The endosymbiotic theory helps to explain the origin of which structures?
The endosymbiotic theory explains the origin of mitochondria and chloroplasts in eukaryotic cells. It posits that these organelles were once free-living prokaryotic organisms that entered into a symbiotic relationship with ancestral eukaryotic cells. Over time, they became integrated and essential components of the cell, leading to the complexity of eukaryotic life. This theory is supported by evidence such as the presence of their own DNA and double membranes.
When was the endosymbiotic theory proposed?
The endosymbiotic theory was proposed in the 1960s by Lynn Margulis to explain the origin of eukaryotic cells. It suggests that eukaryotic cells evolved through a mutually beneficial relationship between primitive prokaryotic cells.
Explain how protists differ from other organisms?
All protists are eukaryotic (have a nucleus), most live in water. They are the "ancestor organisms" because they were the first organisms ever to exist.Protists are simply organisms that don't fit into any of the other kingdoms.The great diversity of form, habitat, mode of nutrition, and life history exhibited by eukaryotes suggests they evolved several times from various groups of prokaryotes. This makes the Protista a polyphyletic group. Eukaryotes are generally larger, have a variety of membrane-bound organelles, greater internal complexity than prokaryotic cells, and has a secialized method of cell division (meiosis) that is a prelude to true sexual reproduction. Protists might be viewed as a group from which the other eukaryotic kingdoms evolved.
Explain why a plant cell classified as a eukaryotic cell?
To explain how a plant cell is eukaryotic rather than prokaryotic, consider the definition of both words. What are the similarities and differences between the two cell types? Here are two places to start: what is found inside each cell type and how does each type reproduce itself?
Is a eubacterium a type of eukaryotic explain?
No, Eubacteria are prokaryotic. The difference between eukaryotic organisms and prokaryotic organisms is fairly simple. It all has to do with cell structure: Eukaryotes: - Have Nucleus - Have Membrane-bound organelles - Usually found in multi-cellular organisms. Prokaryotes: - Have no nucleus, instead they just have a mass of DNA floating inside. - Do not have membrane-bound organelles, just robosomes. - Usually are uni-cellular and have some sort of propulsion device, such as a flagellum.

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.
What does the theory of endosymbiosis explain?
concerns the origins of mitochondria and plastids (e.g. chloroplasts), which are organelles of eukaryotic cells. According to this theory, these organelles originated as separate prokaryotic organisms which were taken inside the cell as endosymbionts. Mitochondria developed from proteobacteria (in particular, Rickettsiales or close relatives) and chloroplasts from cyanobacteria. concerns the origins of mitochondria and plastids (e.g. chloroplasts), which are organelles of eukaryotic cells.

Explain the effect of penicillin on prokaryotic and eukaryotic cells?
Penicillin inhibits the synthesis of bacterial cell walls by targeting the enzymes involved in their production, which are specific to prokaryotic cells. In contrast, eukaryotic cells have different cell wall structures and are not affected by penicillin. This makes penicillin selectively toxic to bacteria, making it an effective antibiotic while sparing eukaryotic cells.

human bones are eukaryotic cells as they contain well developed nucles.

Which theory tries to explain the origin of endoplasmic reticulum nuclear membrane?
The theory of endosymbiosis which believes that nuclear membranes and organelles such as the mitochondrian have evolved from a semi"mutation" in which a prokaryotic cell was engulfed by a eukaryotic cell and instead of being digested it survived and has evolved into key features of the eukaryotic cell. Evidence for this is the fact that the mitochondrian have their own ribosomes ( of which are the prokaryotic variety) and their own DNA which allow them to make their own proteins that can be used in synthesis of adenosine triphosphate (ATP)
