Which domain contains organisms with a nucleus?

Eukarya
The third domain, Eukarya, consists of organisms whose cells have a nucleus. It’s also the only domain that contains multicellular and visible organisms, like people, animals, plants and trees.

Which domain contains organisms that do not have a nucleus?

archaea
archaea, (domain Archaea), any of a group of single-celled prokaryotic organisms (that is, organisms whose cells lack a defined nucleus) that have distinct molecular characteristics separating them from bacteria (the other, more prominent group of prokaryotes) as well as from eukaryotes (organisms, including plants and …

Do all organisms have a nucleus?

Only the cells of advanced organisms, known as eukaryotes, have a nucleus. Generally there is only one nucleus per cell, but there are exceptions, such as the cells of slime molds and the Siphonales group of algae. Simpler one-celled organisms (prokaryotes), like the bacteria and cyanobacteria, don’t have a nucleus.

What 3 domains are all organisms classified into?

The three domains are the Archaea, the Bacteria, and the Eukarya. Prokaryotic organisms belong either to the domain Archaea or the domain Bacteria; organisms with eukaryotic cells belong to the domain Eukarya.

Do eubacteria have a nucleus?

Eubacteria are prokaryotic microorganisms consisting of a single cell lacking a nucleus and containing DNA is a single circular chromosome. Eubacteria can be either gram-negative or gram-positive, they have economic, agricultural, and medical importance.

Do archaea have a nucleus?

Archaea and bacterial cells lack organelles or other internal membrane-bound structures. Therefore, unlike eukaryotes, archaea and bacteria do not have a nucleus separating their genetic material from the rest of the cell.

Does fungi have a nucleus?

Fungi spend much of their lives with only a single nucleus. This cell with two nuclei takes on a life of its own and divides many times to form a mushroom. Each mushroom cell contains a copy of each parent nucleus.

Which domain includes organisms that have a nucleus a cell membrane and mitochondria?

eukaryote. Eukaryotes are organisms whose cells contain a nucleus and other membrane-bound organelles. There is a wide range of eukaryotic organisms, including all animals, plants, fungi, and protists, as well as most algae.

Does bacteria have a nucleus?

Bacteria lack a membrane-bound nucleus and other internal structures and are therefore ranked among the unicellular life-forms called prokaryotes.

Does prokaryotic cell has nucleus?

Prokaryotes are organisms whose cells lack a nucleus and other organelles. The DNA in prokaryotes is contained in a central area of the cell called the nucleoid, which is not surrounded by a nuclear membrane.

Do eukaryotic cells have a nucleus?

Eukaryotes are organisms whose cells contain a nucleus and other membrane-bound organelles. In eukaryotes, the cell’s genetic material, or DNA, is contained within an organelle called the nucleus, where it is organized in long molecules called chromosomes.

Do protists have a nucleus?

Protists are a diverse collection of organisms. While exceptions exist, they are primarily microscopic and unicellular, or made up of a single cell. The cells of protists are highly organized with a nucleus and specialized cellular machinery called organelles.
