 Eukaryote. Eukaryotes are organisms whose cells have a nucleus enclosed within membranes, unlike prokaryotes, bacteria and archaea. Eukaryotes belong to the domain eukaryote or eukaryate. Their name comes from the Creepy. Do you, well or true, and carrion, nut or kernel? Eukaryotic cells also contain other membrane-bound organelles such as mitochondria and the Golgi apparatus, and in addition, some cells of plants and algae contain chloroplasts. Unlike unicellular archaea and bacteria, eukaryotes may also be multicellular and include organisms consisting of many cell types forming different kinds of tissue. Animals and plants are the most familiar eukaryotes. Eukaryotes can reproduce both asexually through mitosis and sexually through myosis and gamete fusion. In mitosis, one cell divides two produced to genetically identical cells. In mitosis, DNA replication is followed by two rounds of cell division to produce for haploid daughter cells. These act as sex cells gametes. Each gamete has just one set of chromosomes, each a unique mix of the corresponding pair of parental chromosomes resulting from genetically culmination during myosis. The domain eukaryote appears to be monophyletic, and makes up one of the domains of life in the three's domain system. The two other domains, bacteria and archaea, are prokaryotes and have none of the above features. Eukaryotes represent a tiny minority of all living things. However, due to their generally much larger size, their collective worldwide biomass is estimated to be about equal to that of prokaryotes. Eukaryotes evolved approximately 1.6 to 2.1 billion years ago, during the prokaryozoic
