CELL PARTS
ORGANELLES FOUND IN BOTH
PLANTS AND ANIMALS
CELL NUCLEUS
LOCATION
In the Center of the Cell surrounded
by cytoplasm
Nucleus
STRUCTURE
 Membrane is
Nuclear Envelope,
 Contains
nucleoplasm
 Nucleolus
 DNA (genetic
material)
FUNCTION
 Houses and
protects the cells
genetic
information DNA
 Site where DNA is
transcribed into
RNA
NUCLEUS
Nuclear Envelope
STRUCTURE
 Double membrane
made of two
phospholipid
bilayers
 Contain Nuclear
Pores-passageway
for RNA and other
materials to enter
and leave the
nucleus
FUNCTION
 Separates inside of
nucleus from
cytoplasm
 Controls what
enters and leaves
the nucleus
 Protects the
genetic material DNA
CHROMATIN “BLUEPRINT OF THE
CELL”
STRUCTURE
Thin uncoiled strands of
DNA and Protein
(LOOKS LIKE Spaghetti)


This is the form that
DNA spends most of its
life.
FUNCTION


Structures that carry
the genetic information.
In this form
transcription can be
performed (making a
copy of mRNA)
CHROMOSOMES “BLUEPRINT OF
THE CELL”
STRUCTURE



Condensed form of DNA
and Proteins
Looks like an X
(BOW-TIE PASTA)
Form Chromatin (DNA)
takes right before cell
division
FUNCTION
Structures that carry
the genetic information.
(Instructions for cells
activities)


It is condensed so DNA
is easier to separate
during cell division
NUCLEOLUS
STRUCTURE

Dense area within
the nucleus
FUNCTION



Made of protein and
rDNA
Creates Ribosomal
RNA
Makes up
Ribosomes (sent
to Cytoplasm)
NUCLEOPLASM
STRUCTURE


Cytoplasm within
nucleus, surrounds
chromatin and
nucleolus
Jelly-like material
FUNCTION

Contains enzymes
and nucleotides for
DNA replication and
rRNA(ribosomal
RNA) synthesis
