1. CELL PARTS ORGANELLES FOUND IN BOTH PLANTS AND ANIMALS

2. CELL NUCLEUS LOCATION In the Center of the Cell surrounded by cytoplasm

3. 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

4. NUCLEUS

5. 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

6. 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)

7. 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

8. NUCLEOLUS STRUCTURE  Dense area within the nucleus  Made of protein and rDNA FUNCTION  Creates Ribosomal RNA  Makes up Ribosomes (sent to Cytoplasm)

9. 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
