Answer 2

1. 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.
2. Eukaryotic DNA is linear; prokaryotic DNA is circular (it has no ends).
3. 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.
4. 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.
5. 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.
6. 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.
7. 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 life
• Do not have a pre-defined nucleus
• Chromosomes are dispersed in the cytoplasm
• Contain no membrane-bound organelles
• Have circular chromosomes and lack histone proteins
• Most metabolically diverse
• Small - typically 0.2-2.0 micrometers in diameter
• Have a primitive cytosketetal structures or don't have a cytoskeleton at all
• Smaller (70S) ribosomes
• Don't undergo meiosis but reproduce sexually by the transfer of DNA fragments through conjugation

Eukaryotic cells:

• More complex, evolved organsims
• Contain true nuclei in which chromosomes are compacted as chromatin
• Contain membrane-bound organelles
• Have linear DNA and contain histone proteins
• Larger - typically 10-100 micrometers in diameter
• Have a complex cytosketeton
• Larger (80S) ribosom
• Reproduce sexually with the use of meiosis

Answer 3

prokaryotic cells: * no nucleus * no membrane covered organelles * circuar DNA * most reffered to as Bacteria * has ribosomes Eukaryotic cells * has a nucleus * has membrane covered organelles * linear DNA * are all other types of cells * has organelles and organelle parts like chloroplast and Mitchondria

Answer 4

Prokaryotic cells do not have a definite nucleus whereas eukaryotes have a nucleus.

Prokaryotic cells the genetic material float freely and is not enclosed within a nuclear membrane whereas in eukaryotic cells the genetic material is enclosed within a nuclear membrane.

Prokaryotic cells do not have membrane bound organelles whereas eukaryotes have membrane bound organelles.

Prokaryotic cells are ten times smaller than the eukaryotic cells.

Answer 5

smallest cell

Euk: have a nucleus

multicellular

have complex cell parts

bigger

Answer 6

The primary difference between eukaryotes and prokaryotes is that eukaryotes have a nucleus that holds their DNA, while prokaryotes do not. There are many, many other differences between the two, however.

Eukaryotic cells can contain several types of membrane enclosed organelles, the most important of which is the nucleus. The nucleus is a membrane-enclosed organelle that contains the cell's DNA. Other examples of similar organelles include mitochondria, endoplasmic reticulum, chloroplasts, and the Golgi apparatus.

Prokaryotic cells, on the other hand, do not contain any membrane-enclosed organelles. They are relatively simpler than eukaryotes. Their DNA is held in a region of the cell known as the nucleoid, but this area does not really differentiate much from the rest of the cytosol, except for the fact that it has DNA.

The structure of DNA differs between eukaryotes and prokaryotes as well. Most prokaryotes' DNA is in a circular form (called ccc-DNA, covalently closed circular DNA) and they only have one single chromosome. Eukaryotes, on the other hand, have DNA that is linear, not circular, and typically have more than one chromosome.

These are just a few of the differences between eukaryotes and prokaryotes.

Answer 7

Eukaryotic cells are usually larger than prokaryotic cells.

Prokaryotic cells have a simple, circular DNA molecule; Eukaryotic cells have DNA in many chromosomes (DNA in eukaryotes is also more complex and includes histone proteins).

Prokaryotic cells have no mitochondria, chloroplasts, or intracellular movement. Eukaryotes use mitochondria and chloroplasts for metabolism. Eukaryotes also exhibit intracellular movement, such as phagocytosis, movement of chromosomes, and cytoplasmic streaming.

Answer 8

Basically, a prokaryotic cell is smaller, has a cell wall, has no nucleus, and its DNA winds around all over inside the cell

A eukaryotic cell is bigger, has no cell wall, and its DNA is contained within a nucleus.

Answer 9

They are both cells that are in certain organisms. They differ in many ways but the main way is that a prokaryotic cells lacks a nucleus while a eukarote cell contains a necleus. A necleus may also be called a nuclei.

Answer 10

A prokaryotic cell has no organized nucleus. It is much less complex than a eukaryotic cell, and lacks organelles. Eukaryotic cells have organelles. That makes a nice rhyme.
