What is the best evidence that all life evolved from prokaryotic rather than eukaryotic ancestors?
The oldest fossil form of life known is prokaryotic (Archeabacterias)
How do eukaryotic compare in size to prokaryotes?
Prokarotes are single-celledbacterium and eukaryotes are plants, animals, and fungi. So eukaryotes are a whole lot larger than prokaryotes.
Why are prokaryotes older then eukaryotes?
Prokaryotes are more than 2 billion years older than eukaryotes.
What organelle is found in animal cells but not in prokaryotic cells?
Mitochondrianucleuscholorplastsgolgi apparatuslysosomesvacuolesnucleoluscentriolesRough endoplasmic reticulumsmooth endoplasmic reticulum
Is a euglena prokaryotic or eukaryotic?
Euglena (and other protists) are EukaryoticNOT prokaryoticEuglena are considered eukaryotic. It can be horrible to have the "prokaryotic" answer be the only reply to this question. Please check SCIENCE sources (dont even just believe me)http://en.wikipedia.org/wiki/Euglenahttp://en.wikipedia.org/wiki/Protistscience journalshttp://www.nature.com/nature/journal/v438/n7064/full/438008b.htmlhttp://www.nature.com.ezproxy.tamu.edu:2048/nature/journal/v438/n7064/full/438008b.html
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.
Which organelle indicates that eukaryotic cells have evolved from prokaryotic cells?
The mitochondria and the chloroplast provide evidence that eukaryotic cells may have evolved from prokaryotic cells.
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
What is the best evidence that all life evolved from prokaryotic rather than eukaryotic ancestors?

Which is used as evidence for the idea that multicellular organisms evolved from prokaryotes?
Mitochondria and chloroplasts have their own DNA
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
What represents Eukaryotic cells?
The primary identifying feature of the eukaryotic cell is the presence of a nucleus, which is the most important intracellular structure and encloses the cells genetic material. In addition, there are other complex organelles like the endoplasmic reticulum and the Golgi complex that are more evolved in eukaryotic cells compared to their prokaryotic counterparts.

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)
