A prokaryote cell has no distinct nucleus with a membrane and neither does it have other specialized organelle.
In a eukaryotic cell, the genetic material is DNA in the form of chromosomes which are found within a distinct nucleus.
Examples of prokaryotes Streptomyces soil bacteria (from which streptomycin antibiotic is derived), Escherichia coli bacterium and Streptococcus bacteria (which causes strep sore throat).
Examples of Eukaryotes include protozoa such as amoeba, fungi, plants, animals and generally all multicellular organisms.

Most of the people stang by a bee or wasp experience a localized reaction and only 3% of the people will exhibit an allergic reaction. The normal localized reaction includes reddening and swelling of the skin, along with a local itching and pain.
Although these reactions will probably start disappearing within a few hours, there are several things that the person could do to alleviate the pain and discomfort. The most important thing to do is to apply ice or cold compresses to the affected area, to reduce the body's inflammatory response.
