The nucleus
• The nucleus was the first organelle
to be discovered .The nucleus also
known as the control center is a
membrane enclosed organelle found
in eukaryotic cells.
• It contains most of the cell’s genetic
material.
• The main structures making up the
nucleus is the nuclear envelope a
double membrane that encloses the
entire organelle.
The Nucleolus
• The nucleolus is a non-membrane
bound structure composed of
proteins and nucleic acids found
within the nucleus.
• The ribosomal RNA is transcribed in
the nucleolus.
• There are three main parts that are
recognized: the fibrillar centers, the
dense fibrillar component, and the
granular components.
The cell nucleus
• The function of the
nucleus is to maintain
the integrity of the
genes and to control
the activities of the
cell by regulating gene
expression.
• The nucleus is the
control center of the
cell.
• The cell nucleus has
the directions for the
proteins.
The nucleolus
• The nucleolus
is the main part
of the cell that
produces the
ribosomes that
make the
proteins.
