All cells have nuclei (plural of "nucelus"). It's their command center. A cell without a nucleus would be like a person with no brain.
The cells of eukaryotes will contain a nucleus.
Nuclei do not contain cells, cells contain nuclei (normally, one nucleus per cell).
bacterial cells do not contain nuclei and are known as prokaryotes. However a special case is red blood cells which do not contain nuclei either and are known as denucleated
Yes, plant cells contain a nucleus.
This theory is false. Red blood cells do not contain a nucleus.
The nucleus
No they don't. Eukaryotic cells are the ones that contain a nucleus. However, just because prokaryote cells don't contain a nucleus, they still contain DNA. It just floats freely in the cytoplasm.
Yes, animal cells - including octopus cells - contain a nucleus.
Prokaryotic cells lack a definite nucleus and membrane- bound organelles while eucaryotic cells have a definite nucleus.
No. Red blood cells (RBC) for example, do not contain a nucleus. Also, prokaryotes do not.
Prokaryotes are (mostly) unicellular organisms without an nucleus.Humans on the other hand are multicellular eukaryotes. Our cells contain nuclei EXCEPT for red blood cells. These do not contain a nucleus in order to be able to transport more oxygen.
No. Plants, animals, and fungi are all Eukaryotes, which means they are all composed of cells containing a nucleus. Bacteria and Archaea are both Prokaryotes, which means their cells do not contain a nucleus.
