Definition of NucleusDefinition of Nucleus 1. Cell Nucleus is a membrane-

enclosed cell organelle that can be found in all eukaryotic

cells. (Wikipedia 2009)

(Dan Stowell (MCLD) 2009)

Definition of NucleusDefinition of Nucleus 1-1. *Only eukaryotic cells

have nucleus. Prokaryotic cells do not contain a cell nucleus of membrane bound organelles.

-Nucleoplasm-Nucleoplasm is one of the types of

protoplasm. It is covered by the nuclear membrane. This part is a stinky liquid that surrounds the chromosomes and nucleoli.

-Nucleolus-Nucleolus is usually in the center of the Nucleus. It is composed of protein and

nucleic acids. *Many people think Nucleus and Nucleolus are the same thing, but they

aren’t. (Wikipedia, 2009)
