Two, now that the designation Monera is defunct. They are.
Eubacteria and Archaea.
There are two main kinds of organisms that have prokaryotic cells: Bacteria and Archaea. These organisms lack a true nucleus and other membrane-bound organelles in their cells.
Prokaryotic cells are bacteria and archaea. They are the single celled organism with no nucleus and prokaryotic cells are asexual.
Prokaryotic
The two basic kinds of cells are prokaryotic cells and eukaryotic cells. Prokaryotic cells do not have a nucleus or membrane-bound organelles, while eukaryotic cells have a nucleus and other membrane-bound organelles.
The two basic kinds of cells are prokaryotic (bacteria) and eukaryotic cells, a eukaryotic cell has a nucleus and organelles, but prokaryotic don't have a nucleus and have ribosomes instead of organelles.
There are two main types of cells, prokaryotic and eukaryotic. Prokaryotic cells do not contain a nucleus, these feature cells such as bacteria,archaea, and protists. To be more specific, prokaryotic cells do not have a membrane around their genetic material.
Prokaryotic cells have no nucleus. In the human body, mature erythrocytes (red blood cells) have no nucleus.
One piece of evidence supporting the claim that there are different kinds of cells is the distinct structure and function of prokaryotic and eukaryotic cells; for example, eukaryotic cells have membrane-bound organelles, while prokaryotic cells do not. Additionally, specialized cells like neurons and muscle cells demonstrate varied functions and structures, highlighting the diversity of cell types within multicellular organisms. These differences underscore the complexity and specialization of cellular life.
The nucleus of the bacterial cell is not well-organised like the cells of the multicellular organisms. There is no nuclear membrane. The cells having nuclear material without nuclear membrane are termed Prokaryotic cells. The organisms with these kinds of cell are called Prokaryotes(pro:primitive; Karyon: nucleus). Examples are bacteria and blue green algae.The cells, like onion cells and check cells having well-organised nucleus with a nuclear membrane are designated as Eukaryotic cells. All organisms other than bacteria and blue green algae are called Eukaryotes. (eu: true ; karyon: nucleus).
No, all the "protists" are nucleate, and so are eukaryotic.
Ribosomes are found in both prokaryotic and eukaryotic cells. They are the cellular structures responsible for protein synthesis.
Both kinds of cells have cytoplasm. The difference between eukaryotic and prokaryotic cells is whether it has a nucleus or not. A eukaryotic cell has one, and a prokaryotic cell doesn't. Both have cytoplasm, which is the gel like substance in which the organelles are held.
