Because it is an organelle. Others are organelles too
mitochondria, and chloroplasts.
Contain genes
There are several organelles that the cell nucleus works with. The cell nucleus works with the centriole, centrosome, lysosome, mitochondria, vacuole, ribosomes, and the endoplasmic reticulum.
prokarotype isSingle celled organisms that do not have a nucleus,mitochondria or any other membrane bound organelles.
mitochondria, nucleus, cytoskeleton (but cytoskeleton should not count as an organelle since it is just a protein network in cytoplasm). Sperm cells probably also have some endoplasmic reticulum and some other organelles.
They are good examples.They are double membranous organelles. Golgi bodies,nucleus,ribosomes, endoplasmic reticulumn are some other
DNA is mainly found in the nucleus of the cell. Of course, it can also be found in other organelles such as the mitochondria (therefore it is called mitochondrial DNA).
It has no membrane bound organelles and it's DNA is not kept in a nucleus or associated with histones
Absence of nucleus , mitochondria and other membrane bound organelles indicate prokaryotic cell .
Mitochondria are organelles and have no organelles of their own. They are inside a cell with other membrane bound organelles.
The main DNA in the cell is found in the nucleus. DNA is also found in two other organelles - the mitochondria and the chloroplasts.
All organelles, including nucleus, mitochondria, ribosome, and every other organelles are found within the cytoplasm.
