Vocabulary: Prokaryotes – don’t have nuclear envelope surrounding their DNA, major distinguishing feature of prokaryotes. Included are all the bacteria. Eukaryotes – organisms that have cells in which the genetic material is located in a membrane- bound nucleus. They can be unicellular or multicellular. Haploid – Haploid cells (N) have one complete set of chromosomes. In animals, gametes (sperm and eggs) are haploid. A cell with one copy of each chromosome. Diploid – Diploid cells (2N) have two complete sets of chromosomes. The body cells of animals are diploid. Haploid cells have one set of daughter cells which means they have 23 chromosomes where as diploid cells have two set of daughter cells meaning they have 23 pairs of chromosomes (46 chromosomes). Chromosomes – a structural organization of genetic material. Chromosomal number – Usually there are 23 pairs of chromosomes (46 in total) in all the body cells except the egg and sperm. Karyotype
