1. Cell Structure and Function Parts of a Cell: Organelles

2. I. Types of Cells A. Prokaryotic Cells 1.Pro = “Before”, Karyo = “Nucleus” 2. No organized nucleus & simple structure 3. Examples: Bacteria, Cyano-bacteria B. Eukaryotic Cells 1.Eu = “Good”, Karyo = “Nucleus” 2.Membrane bound nucleus & structures called organelles 3. Plant and Animal cells

3. II. Organelles A. Nucleus 1. Control center of the cell 2. Starts cell division and contains DNA and RNA 3. Surrounded by a nuclear membrane

4. Organelles B. Cell Membrane 1. A cell membrane separates the inside of the cell from the outside 2.They are not-rigid, but fluid and semi-permeable 3.They control which molecules come in and out of the cell

5. Organelles C. Mitochondria 1.“Power House” of the cell 2. Carry out respiration a. Breaks down the glucose and converts it into ENERGY and CO2

6. Organelles D. Endoplasmic Reticulum 1.Network of folded membranes in a cell 2. Manufacture and transport chemicals throughout the cell 3. Two types: Smooth ER and Rough ER

7. Organelles E. Golgi Bodies 1. System of flattened membranes 2. Responsible for packaging and processing proteins 3. Works with the Endoplasmic Reticulum

8. Organelles F. Ribosomes 1. Ribosomes are where all proteins are made 2. Can be found in the cells nucleus, rough endoplasmic reticulum, or free floating

9. Organelles G. Lysosomes 1. Digest molecules; old organelles, and foreign substances

10. Organelles H. Cytoplasm 1.Jelly-like fluid that fills the cell I. Cytoskeleton 1.Internal structure or skeleton of a cell 2.Gives strength to cell 3. Anchors organelles in place

11. III. Organelles: Plant Cells A. Plant cells have a few additional Organelles

12. Organelles:Plant Cell B. Cell Wall 1. Rigid layer around a plant cell 2. Gives structure and form to plant cells 3. Made of Cellulose

13. Organelles: Plant Cell C. Chloroplast 1.“Power house” for a plant cells 2.Converts sunlight into usable energy for the plant 3.Contains a large amount of green pigment; responsible for the plant color

14. Organelles: Plant Cell D. Vacuole 1.Store enzymes 2. Remove and store metabolic waste from the cell 3. Holds water
