1. Cells and all that Jazz H. Smith

2. Cell Theory: 3 parts Cells are the basic unit of life. All living things are made of cells. All cells come from pre-existing cells

3. Organelles “organs” of the cell Have special functions within cell

4. Nucleus Control Center Contains DNA All eukaryotic cells have one

5. Nucleolus Center of nucleus Creates Ribosomes

6. Nuclear envelope Surrounds nucleus, controls movement in and out of nucleus

7. Nuclear Pore Holes in nuclear envelope, allows things to enter and leave nucleus

8. Mitochondria “Powerhouse” of cell Produces energy (ATP) Membrane bound Has own DNA

9. Smooth Endoplasmic Reticulum (SER) Transports molecules Detoxification Makes lipids

10. Rough Endoplasmic Reticulum (RER) Protein alterations Transport of molecules Rough=has ribosomes attached

12. Ribosomes Protein factories Create proteins Free or attached to rough ER

13. Golgi Apparatus Packaging of proteins, lipids, and carbs Post office of cell

14. Vacuole Storage Very large in plant (stores water)

15. Lysosome Recycling center Contains enzymes for digestion Reuse old cell parts

16. Vesicle Taxi cab Transports molecules to and from cell membrane

17. Chloroplast PLANTS ONLY Site of Photosynthesis Contain chlorophyll pigment (green)

18. Cell Membrane Surrounds cell Barrier, controls what moves in/out of cell Made of aPhospholipid bilayer Semi-permeable

20. Cell Wall PLANT ONLY Surrounds cell (outside membrane) Protection

21. Cytoplasm Gel inside cell Surrounds organelles Cytosol: fluid portion of cytoplasm

22. Centrioles ONLY ANIMAL “midwives” Assist in cell division

23. Chromatin Condensed DNA Found in nucleus

24. Microtubule Protein tubes, make up cytoskeleton of cell Support Thick

25. Microfilaments Thin Make up cytoskeleton Flexible, allow cells to move

26. Cilia Small hairs for movement Animal only

27. Flagella Tail-like structure Movement Animal only
