Chromosomes were first observed in plant cells by Carl Wilhelm von Nägeli in 1842.
The chromosomes are depicted (by rearranging a photomicrograph) in a standard format known as a karyogram or idiogram: in pairs, ordered by size and position of centromere for chromosomes of the same size.
The basic number of chromosomes in the somatic cells of an individual or a species is called the somatic number and is designated 2n.
