No.
Prokaryotes do not have a nucleus. they might have nuclear material but it's not membrane in closed so it is not regarded as a nucleus.
Prokaryotic cells have no nucleus, they are only a bacteria cell, and they have circular DNA.
The cells of eukaryotes will contain a nucleus.
Nuclei do not contain cells, cells contain nuclei (normally, one nucleus per cell).
No
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.
Nucleus, among other membrane-bound organelles.
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.
