Moneran
The kingdom Protista does not have a nucleus. It includes organisms like bacteria, which are prokaryotic and lack a membrane-bound nucleus in their cells.
Cells in the kingdom plantae do have a nucleus. This is true for all Eukaryotic cells. Plant cells have an enclosed nucleus.
Protista is a kingdom of eukariya.So they have a nucleus.
If the cell contains peptidoglycan but contains no nucleus, the cell is a bacteria, and therefore belongs in either kingdom eubacteria or kingdom archaebacteria.
Probably Protista, because there are evidences that suggests they were the first eukaryotes to be developed.
There is no such thing as a bacterium with a nucleus. Single-celled organisms with a nucleus are in the kingdom protista.
The animal kingdom that lacks a nucleus is the kingdom Monera, which includes bacteria. Bacteria are prokaryotic organisms, meaning they do not have a membrane-bound nucleus like eukaryotic organisms.
Protoctista are eukaryotic, meaning they have a true nucleus. Monera are prokaryotic, meaning they have no nucleus.
Unicellular organisms with no nucleus are called prokaryotes; they do not have a kingdom classification, but have two domains: Archaea and Bacteria.
* Kingdom Animalia, Phylum prokaryotae. i disagree, its kingdon prokaryote
The kingdom that has only one cell and lacks a nucleus is Monera. Monera includes unicellular prokaryotic organisms such as bacteria, which have a simple cell structure without a membrane-bound nucleus.
Cells in organisms that are a part of the kingdom Animalia do have nucleus. Only cells that are prokaryotic cells do not have nucleus.
