Eukaryote - Wikipedia. The eukaryotes ( / juːˈkærioʊts, - əts / yoo-KARR-ee-ohts, -əts) [5] constitute the domain of Eukarya or Eukaryota, organisms whose cells have a membrane-bound nucleus. All animals, plants, fungi, and many unicellular organisms are eukaryotes.
Context. Life arose on Earth once it had cooled enough for oceans to form. The last universal common ancestor (LUCA) was an organism which had ribosomes and the genetic code; it lived some 4 billion years ago. It gave rise to two main branches of prokaryotic life, the bacteria and the archaea.
An eukaryote is an organism with complex cells, or a single cell with complex structures. In these cells the genetic material is organized into chromosomes in the cell nucleus. Animals, plants, algae and fungi are all eukaryotes. There are also eukaryotes amongst single-celled protists.
May 28, 2024 · eukaryote, any cell or organism that possesses a clearly defined nucleus. The eukaryotic cell has a nuclear membrane that surrounds the nucleus, in which the well-defined chromosomes (bodies containing the hereditary material) are located.
A eukaryote is an organism whose cells contain complex structures enclosed within membranes. The defining membrane-bound structure that sets eukaryotic cells apart from prokaryotic cells is the nucleus , within which the genetic material is carried.
Apr 27, 2017 · Eukaryotes are organisms whose bodies are made up of eukaryotic cells, such as protists, fungi, plants and animals. Eukaryotic cells are cells that contain a nucleus and organelles, and are enclosed by a plasma membrane.
The leading hypothesis for the origin of eukaryotes, called the endosymbiotic theory, is that eukaryotes arose as a result of a fusion of Archaean cells with bacteria, where an ancient Archaean engulfed (but did not eat) an ancient, aerobic bacterial cell.
What are the key features of eukaryotic cells? Unlike prokaryotic cells, eukaryotic cells have: A membrane-bound nucleus, a central cavity surrounded by membrane that houses the cell’s genetic material. A number of membrane-bound organelles, compartments with specialized functions that float in the cytosol.
Eukaryotes are organisms whose cells contain a nucleus and other organelles. There is a wide range eukaryotic organisms, including all animals, plants, fungi, protists and most...
A eukaryote (or eucaryote) is an organism with a complex cell or cells, in which the genetic material is organized into a membrane-bound nucleus or nuclei. Eukaryotes comprise animals, plants, and fungi —which are mostly multicellular—as well as various other groups that are collectively classified as protists (many of which are unicellular).
