what are the differences between prokaryotes eukaryotes and viruses?
21198
Short story: Human cells are eukaryotic which means they are more complicated, bacteria cells are prokaryotic which means they are simpler and viruses are not even cells at all, they are just genetic material in a protein shell. ... Viruses are more like parasites they need a host cell to reproduce.

Eukaryotes and prokaryotes both have DNA, but it is only enclosed in a membrane in eukaryotic cells. ... In general, prokaryotic cells do not have a true nucleus or membrane-bound organelles, whereas eukaryotic cells contain both a nucleus and organelles enclosed by membranes.

Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions.

The main difference between eukaryotic and prokaryotic cells is that eukaryotic cells have a nucleus. The nucleus is where cells store their DNA, which is the genetic material. ... All prokaryotes are single-celled (unicellular) organisms. Bacteria and Archaea are the only prokaryotes.

Prokaryotic cells differ from eukaryotic cells in that their genetic material is contained in a nucleoid rather than a membrane-bound nucleus. ... Some prokaryotic cells are able to form endospores through sporulation to survive in a dormant state when conditions are unfavorable.

Comparing prokaryotes and eukaryotes The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. ... Prokaryotes, on the other hand, have no membrane-bound organelles. Another important difference is the DNA structure.

Comparing prokaryotes and eukaryotes The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information.

Viruses are a family of pathogens that infect a host by replicating the viral genome in them. The impact of viruses i.e. ease of infection, defense plans, etc. on prokaryotic and eukaryotic cells is different since the structures of the hosts are different.

Prokaryotic cells are much smaller and much simpler than eukaryotic ones. They have no true membrane bound nucleus and no other membrane bound organelles. They also have a cell wall, smaller ribosomes and may have other features.

The division between prokaryotes and eukaryotes is usually considered the most important distinction or difference among organisms. The distinction is that eukaryotic cells have a "true" nucleus containing their DNA, whereas prokaryotic cells do not have a nucleus.

In contrast to prokaryotic cells, eukaryotic cells are highly organized. Bacteria and archaea are prokaryotes, while all other living organisms — protists, plants, animals and fungi — are eukaryotes.

Viruses are not cells at all, so they are neither prokaryotes nor eukaryotes. ... Viruses cannot reproduce by themselves. Instead, they infect living hosts, and use the hosts' cells to make copies of their own DNA.

Eukaryotes have larger cells and their DNA is contained in a nucleus. ... Viruses may carry DNA or RNA but do not metabolize. Bacteriophages cannot replicate without a prokaryotic host.

Eukaryotic cells are generally bigger than prokaryotic cells. This allows eukaryotes to have organelles, have slower turnover rates of macromolecules, and requires the presence of mechanisms to move things around the cell.

The division between prokaryotes and eukaryotes is usually considered the most important distinction or difference among organisms. The distinction is that eukaryotic cells have a "true" nucleus containing their DNA, whereas prokaryotic cells do not have a nucleus. ... Prokaryotes lack mitochondria and chloroplasts.

Both organisms are composed of cells, the basic unit of life, with each cell surrounded by a cell membrane. The biggest difference between prokaryotes and eukaryotes is that eukaryotes have a nucleus. They also have other membrane structures called organelles.
