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
This theory is false. Red blood cells do not contain a nucleus.
Yes, plant cells 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.
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.
No. Red blood cells (RBC) for example, do not contain a nucleus. Also, prokaryotes do not.
