1) The antibodies destroy the antigen (pathogen) which is then swallowed and digested by macrophages.
2) White blood cells can produce antitoxins which destroy the toxins that are otherwise known as poison.

Eukaryotic: mitosis: prokaryote: binary fission
Eukaryotic cells reproduce by mitosis while prokaryotes reproduce by binary fission.
Eukaryotes include fungi, plants, and animals and are complex in structure. They have a nucleus, several organelles and more DNA (deoxyribonucleic acid). Eukaryotic cells undergo mitosis; a form of cell division that usually produces two similar daughter cells with the same genetic component as the parent cell. Prokaryotes include bacteria, and archaea, and are quite simple in structure. They do not have organelles or nucleus, but they have only a small amount of DNA. Prokaryotes undergo binary fission; a type of asexual reproduction in which there is replication and segregation of a single DNA molecule.
The key to mitosis occurring is the presence of a nucleus.
