"In cell Biology, the nucleus (pl. nuclei; from Latin nucleus or nuculeus, meaning kernel) is a membrane-enclosed organelle found in eukaryotic cells." - Wikipedia article: "Nucleus (cell)"
So yes, a nucleus is an organelle. Although my textbook doesn't really seem to consider the nucleus as an organelle, it treats it like its something separate... but it makes more sense that its considered an organelle.
Any and all eukaryotic cells have nuclei and membrane-bound organelles.
No
Yes
Yes
Can I has nucleus? Eukaryotic cells contain nuclei and organelles, while prokaryotic cells do not.
red blood cells gradually become filled with hemoglobin, their nuclei and other organelles are forced out. Thus, mature red blood cells do not have nuclei.
the evolution of cells with nuclei and organelles
Nuclei.
As red blood cells gradually become filled with hemoglobin, their nuclei and other organelles are forced out. Thus, mature red blood cells do not have nuclei.
Yes, Mitochondria are organelles inside of Cells, which contain Nuclei.
eukaryotes plant cells or animal cells
Plants and animals have eukaryoteic cells, these cells have membrane bound organelles and nuclei. Bacteria have prokaryoteic cells. These cells lack membrane bound organelles and no nuclei.
