Eukaryote definition: any organism of the domain Eukaryota, having as its fundamental structural unit a cell type that contains specialized organelles in the cytoplasm, a membrane-bound nucleus enclosing genetic material organized into chromosomes, and an elaborate system of division by mitosis or meiosis, characteristic of all life forms except bacteria and other primitive microorganisms..
They are called prokaryotes. Virtually all the life we see each day — including plants and animals — belongs to the third domain, Eukaryota. Eukaryotic cells are more complex than prokaryotes, and the DNA is linear and found within a nucleus. Eukaryotic cells boast their own personal “power plants”, called mitochondria.
The meaning of EUKARYOTE is any of a domain (Eukarya) or a higher taxonomic group (Eukaryota) above the kingdom that includes organisms composed of one or more cells containing visibly evident nuclei and organelles.
The major eukaryote supergroups. These share a last eukaryote common ancestor (LECA), but their descent and interrelationship remains uncertain. With each supergroup some examples of key lineages are shown: there are many others. SAR supergroup includes Stramenopiles, Alveolates, and Rhizaria. Eukaryote tree is unrooted. From Walker et al. (2011).
Eukaryotic definition: of, relating to, or characteristic of a eukaryote, an organism whose basic structural unit is a cell containing specialized organelles and a membrane-bound nucleus.
May 23, 2018 · eukaryote. eukaryote Organism whose cells have a membrane-bound nucleus, with DNA contained in chromosomes. Making up one of the three domains, eukaryotes include all animals, plants, fungus, and Protoctista. They have a complex cytoplasm with an endoplasmic reticulum, and most of them possess mitochondria. Most plants and algae also possess ...
The Eukaryota include the organisms that most people are most familiar with - all animals, plants, fungi, and protists. They also include the vast majority of the organisms that paleontologists work with. Although they show unbelievable diversity in form, they share fundamental characteristics of cellular organization, biochemistry, and ...
