CELL PARTS
ORGANELLES FOUND IN BOTH PLANTS AND ANIMALS
CELL NUCLEUS
LOCATIONIn 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
Made of protein and rDNA
FUNCTION
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
