List three ways in which prokaryotic cells differ from eukaryotic cells?

∙ 13y ago
1. Nucleus. The main difference is that eukaryotic cells have a nucleus and prokaryotic cells do not. That is really the meaning of the words prokaryotic (before nucleus) and eukaryotic (true nucleus).
2. Organelles. Eukaryotic cells have membrane-bound organelles and prokaryotic cells do not. I say membrane-bound organelles (mitochondrion, lysosomes) because both have ribosomes, which in come texts are considered organelles, but ribosomes are not membrane-bound (surrounded by a membrane).
3. Size. Eukaryotic cells are huge compared to prokaryotic cells. Most eukaryotic cells can be seen in detail with a simple light microscope.
4. Method of reproduction( cell division). Prokaryotic cells divide by binary fission and eukaryotic cells divide by mitosis or meiosis.

∙ 11y agoeukaryote have a nucleus while prokaryotes are cells without a nucleus. Eukaryotes are alive while prokaryotes are not alive.
Example: eukaryotes- animal cells, prokaryotes- viruses (cells that aren't alive)

∙ 9y agoThere are four ways that Prokaryotic can change. The four ways that Prokaryotic can change are not having nucleus, not having membrane bound organelles, having offspring by asexual reproduction and having a single cell instead of multi-cellular.

Three things both eukaryotic and prokaryotic cells have?
The similarities between prokaryotic and eukaryotic cells are; They both contain ribosomes They are both enclosed by plasma membranes They are both filled with cytoplasm and they both have DNA.
What are three main types of work that cells perform and gives examples of each?
there are prokaryotic and eukaryotic cells. Prokaryotic cells are in plants and do photosynthesis, while eukaryotic cells are in animals cells and they just help the organism stay alive. i hope this helped you guys :)
What structural features characterise prokaryotes?
"Prokaryotic cells differ significantly from eukaryotic cells. They don't have a membrane-bound nucleus and instead of having chromosomal DNA, their genetic information is in a circular loop called a plasmid. Bacterial cells are very small, roughly the size of an animal mitochondrion (about 1-2µm in diameter and 10 µm long). Prokaryotic cells feature three major shapes: rod shaped, spherical, and spiral. Instead of going through elaborate replication processes like eukaryotes, bacterial cells divide by binary fission."
What describes a prokaryotic cell?
Prokaryotic cells have ribosomes, plasmids, cytoplasm, plasma membrane, cell wall, and a nucleoid. They do not have a membrane-bound nucleus like Eukaryotes do.
What organelles do both prokaryotic cells and eukaryotic cells have?
Some examples of organelles that could be present in both pro-and eukaryotic cells (it all depends on the species) are a: flagellum, plasmid (rare in eukarytoic cells, but not unheard of) and ribosome.

Which cell is not a eukaryotes Plant cell animal cell Bacteria cell or trees cell?
Tree cells and plant cells are similar, and animal cells differ from the other three (tree, plant, and bacteria). Bacteria are characterized by having round DNA instead of linear DNA. Round DNA is a characteristic of prokaryotic cells and not eukaryotic cells. Thus, bacteria is not a eukaryote. (Note: there are many more differences between eukaryotic cells and prokaryotic cells such as size, organelles....)
Describe the differeneces between a prokaryotic and a eukaryotic cell and identify their parts?
the scanning electron microscope allows scientist to scan the surfaces of cells to learn their three-dimensional shape. the transmission electron microscope allows scientist to study the structures contained within the cell

Are hamsters prokaryotic or eukaryotic?
Plankton can be either eukaryotic or prokaryotic, it's dependent on the specific type of plankton. Plankton are divided into three different categories, Zooplankton, Bacterioplankton and phytoplankton. Zooplankton are eukaryotic.

Is archaebacteria procaryotic or eucaryotic?
Archaebacterias are prokaryotic, although they have more things in common with a eukaryotic cell because they too lack a true nucleus.
Differences between eukaryotic cells and prokaryotic cells are .?
Eukaryotic cells have a true nucleus, bound by a double membrane. Prokaryotic cells have no nucleus. The purpose of the nucleus is to sequester the DNA-related functions of the big eukaryotic cell into a smaller chamber, for the purpose of increased efficiency. This function is unnecessary for the prokaryotic cell, because its much smaller size means that all materials within the cell are relatively close together. Of course, prokaryotic cells do have DNA and DNA functions. Biologists describe the central region of the cell as its "nucleoid" (-oid=similar or imitating), because it's pretty much where the DNA is located. But note that the nucleoid is essentially an imaginary "structure." There is no physical boundary enclosing the nucleoid.Eukaryotic DNA is linear; prokaryotic DNA is circular (it has no ends).Eukaryotic DNA is complexed with proteins called "histones," and is organized into chromosomes; prokaryotic DNA is "naked," meaning that it has no histones associated with it, and it is not formed into chromosomes. Though many are sloppy about it, the term "chromosome" does not technically apply to anything in a prokaryotic cell. A eukaryotic cell contains a number of chromosomes; a prokaryotic cell contains only one circular DNA molecule and a varied assortment of much smaller circlets of DNA called "plasmids." The smaller, simpler prokaryotic cell requires far fewer genes to operate than the eukaryotic cell.Both cell types have many, many ribosomes, but the ribosomes of the eukaryotic cells are larger and more complex than those of the prokaryotic cell. Ribosomes are made out of a special class of RNA molecules (ribosomal RNA, or rRNA) and a specific collection of different proteins. A eukaryotic ribosome is composed of five kinds of rRNA and about eighty kinds of proteins. Prokaryotic ribosomes are composed of only three kinds of rRNA and about fifty kinds of protein.The cytoplasm of eukaryotic cells is filled with a large, complex collection of organelles, many of them enclosed in their own membranes; the prokaryotic cell contains no membrane-bound organelles which are independent of the plasma membrane. This is a very significant difference, and the source of the vast majority of the greater complexity of the eukaryotic Cell. There is much more space within a eukaryotic cell than within a prokaryotic cell, and many of these structures, like the nucleus, increase the efficiency of functions by confining them within smaller spaces within the huge Cell, or with communication and movement within the Cell.Eukaryotic Cells are the largest Cells, while prokaryotic Cells are smaller than eukaryotic Cells. A eukaryotic Cell is about 10 times bigger than a prokaryotic Cell.Eukaryotic Cells have a bi-lipid-layer plasma membrane and an exterior glyco-callyx Cell Coat; prokaryotic Cells have a bi-lipid-layer plasma membrane and an exterior mostly cellulosic Cell Wall.A List:Prokaryotic cells:Most primitive, earliest form of lifeDo not have a pre-defined nucleusChromosomes are dispersed in the cytoplasmContain no membrane-bound organellesHave circular chromosomes and lack histone proteinsMost metabolically diverseSmall - typically 0.2-2.0 micrometers in diameterHave a primitive cytosketetal structures or don't have a cytoskeleton at allSmaller (70S) ribosomesDon't undergo meiosis but reproduce sexually by the transfer of DNA fragments through conjugationEukaryotic cells:More complex, evolved organsimsContain true nuclei in which chromosomes are compacted as chromatinContain membrane-bound organellesHave linear DNA and contain histone proteinsLarger - typically 10-100 micrometers in diameterHave a complex cytosketetonLarger (80S) ribosomReproduce sexually with the use of meiosis
What are the differences between prokaryotic cells and eukaryote cells?
Dont use this Patrice!
What are three examples of eukaryotic organisms?
animal cells and plant cells are examples of Eukaryotes. Such cells can be found almost anywhere. Remember, Eukaryotic cells have a nucleus to them and Prokaryotic cells don't. The inside of your cheek is one of the easiest places to find animal cells if you want to look at them and for eukaryotic plant cells you can use the skin of an onion
