6. NUCLEUS The control center of the cell Largest organelle in animal cells Contains genetic material DNA DNA Nucleolus Nuclear envelope Nuclear pores

7. Copyright Pearson Prentice Hall The nucleolus is where the assembly of ribosomes begins. Nucleolus NUCLEOLUS

9. Mitochondria Singular: Mitochonrion Plural: Mitochondria The “Powerplant” of the cell –Stores energy in the form of ATP MITOCHONDRIA

10. RIBOSOMES Can be attached to Rough ER OR free in cytoplasm. This is where proteins are made! Image from: http://www.biologyclass.net/endoplasmic.jpe

11. Copyright Pearson Prentice Hall Ribosomes Endoplasmic Reticulum Two types Rough ER Has ribosomes protein making Smooth ER No ribosomes attached Makes lipids

12. GOLGI APPARATUS Modify, sort, & package molecules from ER for storage or transport out of cell- like the post office Ships proteins to their final destination. Image from: http://vilenski.org/science/safari/cellstructure/golgi.h

13. LYSOSOMES Digest food, unwanted molecules, old organelles, cells, bacteria, etc. Like trash men: they take out the garbage! Also known as suicide sacs

14. Plant cells: large Animal cells: small Storage space Vacuole VACUOLES
