Mitosis can occur in a diploid nucleus, that is, one containing pairs of chromosomes representing each of its parents or in a haploid one containing a single set of chromosomes. Meiosis, often called reduction division, yields four daughter nuclei with the number of chromosomes reduced to half the original number. The overall result is that one diploid nucleus becomes four haploid nuclei.

LSD is an example of an ergoline derivative. It is commonly produced from lysergic acid, which is made from ergotamine, a substance derived from the ergot fungus on rye, or from ergine (lysergic acid amide), a chemical found in morning glory and hawaiian baby woodrose seeds.SD is typically delivered orally, usually on a substrate such as absorbent blotter paper, a sugar cube, or gelatin. LSD was first synthesized in 1938 by Swiss chemist Dr. Albert Hofmann at the Sandoz Laboratories in Basel as part of a large research program searching for medically useful ergot alkaloid derivatives.
