1. Cell Anatomy Cell Parts & their Function

2. What is a Cell? A cell is the smallest unit that is capable of performing life functions. It is the basic unit of living things.

3. Cell Theory • All living things are made up of cells. • Cells are the smallest working units of all living things. • All cells come from preexisting cells through cell division.

4. Examples of Cells Amoeba Proteus Plant Stem Bacteria Red Blood Cell Nerve Cell

5. Cell Organelles • Cell Parts are referred to as organelles.

6. Cell Wall Most commonly found in plant cells & bacteria Supports & protects cells Cell Wall

7. Cell Membrane • protective layer around all cells • allows food and oxygen into the cell and waste products out of the cell. Cell Wall Cell Membrane

8. Cytoplasm • Gel-like material • Surrounded by cell membrane Cell Wall Cell Membrane Cytoplasm

9. Nucleus • contains instructions for everything cell does; includes DNA Cell Wall Cell Membrane Cytoplasm Nucleus

10. Ribosome • Each cell contains thousands • Make proteins • (Think of it like a battery plant!) • Found on ER & floating throughout the cell Cell Wall Cell Membrane Cytoplasm Nucleus Ribosome

11. Endoplasmic Reticulum (ER for Short) • Moves materials around in cell • (Like a highway) • Smooth type: lacks ribosomes • Rough type : ribosomes embedded in surface Cell Wall Cell Membrane Cytoplasm Nucleus Ribosome ER

12. Mitochondrion • releases energy from food • (Energy Plant) • Controls level of water and other materials in cell Cell Wall Cell Membrane Cytoplasm Nucleus Ribosome ER Mitochondrion

13. Chloroplasts • Found only in plant cells. • Contains green chlorophyll • Where photosynthesis takes place • Helps plant cells make food. Cell Wall Cell Membrane Cytoplasm Nucleus Ribosome ER Mitochondrion Chloroplasts

14. Vacuole • membrane-bound temporary storage spaces • Contains water solution • Help plants maintain shape Cell Wall Cell Membrane Cytoplasm Nucleus Ribosome ER Mitochondrion Chloroplasts Vacuoles

15. Golgi Body • Protein 'packaging plant' • Move materials within the cell • Move materials out of the cell Cell Wall Cell Membrane Cytoplasm Nucleus Ribosome ER Mitochondrion Chloroplasts Vacuoles Golgi Body

16. Make a Cell • Your assignment: • We will make a model of the cell using the materials on the table. • You must use the paper plate as the basis of your cell.
