prokaryote
Organisms that have cells without nuclei are called prokaryotes. This includes bacteria and archaea. Prokaryotic cells do not have a defined nucleus but instead have a nucleoid region where the genetic material is located.
Bacteria are single-celled, and they have cell walls. They do not have nuclei. They are also microscopic.
Yes!
No, in general bacteria do not have nuclei.
prokaryotes
both archaea and bacteria are domains that are made up of prokaryots. prokaryots do not have a nucleus. the only domain that is known to have nuclei is eukarya.
Bacteria are placed in a kingdom by themselves, called Monera, because they are prokaryotic organisms with unique characteristics that separate them from other organisms with nuclei. They have a simple cellular structure lacking membrane-bound organelles and a true nucleus, making them distinct from eukaryotic organisms.
Cheek cells are much larger than bacteria and they have nuclei.
Bacteria are unicellular organisms with no nucleus. They have a cell wall and reproduce asexually through binary fission. Bacteria come in various shapes and sizes, and can be found in almost every habitat on Earth.
Plant and animal cells, being eukaryotic cells, have nuclei. These are not present in bacteria since they are prokaryotic (before-yolk, i.e. before-nucleus) cells by definition. Viruses also do not have nuclei since they are acellular in nature.
all cells have a nuclei
