Bacteria.
The term is confusingly used for both atoms and cells, and are only alike in their locations.In atomic structure, the word was applied in the modern sense in 1912 by Ernest Rutherford, from his experiment that showed a very small solid mass within each atom. The word was used as early as 1844 by Michael Faraday to mean the center of an atom. The word nucleus means 'kernel' which was another term used to describe the central mass, and which was still used for several years after Rutherford's experiments.In cytology, the term 'lumen' for a cell nucleus was used by Antonie van Leeuwenhoek around 1676. In 1831, Scottish botanist Robert Brown used the terms 'aerola' and 'nucleus' to describe the darker spots he saw within orchid cells.
Some unicellular organisms get by fine with no nucleus. The general term for these is prokaryotes. (A few prokaryotes form multicelluar stages, but this is not common.) Most multicellular organisms... and some unicellular organisms... do have cell nuclei. The general term for these is eukaryotes. Some specialized cells in multicellular organisms have no nucleus. For example, mammalian red blood cells have no nucleus. The generic term for any cell without a nucleus, whether a prokaryote or a specialized cell in a eukaryote, is anucleate (which simply means "without a nucleus").

Eukaryote is a term used in biology to refer to organisms whose cells have a true nucleus containing their genetic material, like plants, animals, and fungi. An example sentence could be: "The eukaryote cell of a human is characterized by a well-defined nucleus surrounded by a membrane."
No, not all cells have a nucleus. Prokaryotic cells, such as bacteria, do not have a nucleus, while eukaryotic cells, found in multicellular organisms, have a nucleus that houses the genetic material.
The term you are looking for is eukaryotic. Eukaryotic cells have a defined nucleus that houses the genetic material of the cell.
Gene
The term used to describe organisms that do not have a nucleus is "prokaryotes." Prokaryotes include bacteria and archaea, which are characterized by their simpler cellular structure compared to eukaryotes, which do have a nucleus. Prokaryotic cells lack membrane-bound organelles and typically have a single circular chromosome.

The cells of eukaryotes will contain a nucleus.

prokaryotic
Eukaryotic cells have a true nucleus that encloses genetic material while prokaryotic cells do not have a nucleus. Eukaryotic cells are typically larger and more complex than prokaryotic cells, containing organelles such as mitochondria and the endoplasmic reticulum. Eukaryotic cells are found in plants, animals, fungi, and protists, while prokaryotic cells are found in bacteria and archaea.
no nucleus is INSIDE cells
Eukaryote is a term used in biology to refer to organisms whose cells have a true nucleus containing their genetic material, like plants, animals, and fungi. An example sentence could be: "The eukaryote cell of a human is characterized by a well-defined nucleus surrounded by a membrane."
Cells in organisms that are a part of the kingdom Animalia do have nucleus. Only cells that are prokaryotic cells do not have nucleus.
