an organism with "good" or membrane-bound nuclei having multiple chromosomes; eucaryotes also have other membrane-bound organelles such as mitochondria or chloroplasts, within the cytoplasm enclosed by the outer membrane. Such cells are characteristic of all life forms except primitive microorganisms such as bacteria and blue-green algae. Contrasted with prokaryote.
Organism that contains a defined nucleus; includes all organisms except viruses, bacteria and blue-green algae, which are known as prokaryotes.
(Also eukaryote.) Living organism composed of one or more cells with a distinct nucleus and cytoplasm. Includes plans, animals, fungi and protozoa; excludes bacteria (prokaryotes).
Living organism composed of one or more cells with a distinct nucleus and cytoplasm. Includes all forms of life except viruses and bacteria (procaryotes).
Also spelled eukaryote; a single-celled or multicellular organism whose cells contain a distinct membrane-bound nucleus.
an organism with cells characteristic of all life forms except primitive microorganisms such as bacteria; i.e. an organism with `good' or membrane-bound nuclei in its cells
An organism whose genetic information is, in contrast to prokaryotes (such as bacteria), contained in a separate cellular compartment: the nucleus. Besides algae, fungi and protozoa, all multicellular, cell-differentiating organisms including plants and animals are eukaryotes. In addition to their nuclear genome, all eukaryotic cells contain small additional, extranuclear genomes, which are contained in mitochondria (in all eukaryotes) and in plastids (only in eukaryotes that can perform photosynthesis).
living organisms that have internal, membrane-bounded components in the cells, such as nuclei, chloroplasts (c.f. procaryote)
