1. Cell Theory 1.)All living things are made up of cells. 2.)Cells are the smallest working units of all living things. 3.)All cells come from preexisting cells.

2. Two Cell Categories Prokaryotes v.s. Eukaryotes Pro=NO Eu (you)=Do No nucleus Nucleus No organelles Many organelles Only Bacteria All Other Cells PlantAnimalBacteria

3. Cell The smallest unit capable of performing life functions.

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

7. Cell Parts Organelles- Specialized structures in eukaryotic cells that perform specific functions.

8. Surrounding the Cell

9. Cell Membrane A semi-permeable membrane controls what enters/exits the cell. (plants AND animals) http://library.thinkquest.org/12413/structures.html

10. Cell Wall The cell wall gives the plant cell structure and support http://library.thinkquest.org/12413/structures.html

11. Inside the Cell

12. Nucleus The nucleus is the brain of the cell. Controls cell activities and protects the DNA

13. Chromosomes Chromosomes (made of DNA in the nucleus) have instructions for your traits http://library.thinkquest.org/12413/structures.html

14. Cytoplasm Gel-like mixture called cytoplasm is surrounded by the cell membrane.

15. Endoplasmic Reticulum The Rough Endoplasmic Reticulum moves materials around in cell (has ribosomes attached) http://library.thinkquest.org/12413/structures.html

16. Inside the cell The Smooth Endoplasmic Reticulum helps makes lipids

17. Inside the Cell (honors) slide Mitochondria breaks down food/oxygen to create energy/power in the form of carbohydrates for the cell. Has it’s own DNA like the nucleus (other organelles don’t). Reproduces within the cell based on demand http://library.thinkquest.org/12413/structures.html

18. Inside the Cell Proteins are made by the ribosomes http://library.thinkquest.org/12413/structures.html

19. Golgi Bodies Protein are modified, packaged, sorted and shipped by the Golgi Bodies. http://library.thinkquest.org/12413/structures.html

20. Inside the Cell (honors slide) Photosynthesis (conversion of water, sunlight, and carbon dioxide into carbs) happens in the chloroplast of only plant cells Has it’s own DNA and reproduces within the cell (similar to mitochondira) http://library.thinkquest.org/12413/structures.html

21. Lysosome Lysosomes comes from Golgi Body They breaks down/digest: proteins, nucleic acids, carbohydrates, phospholipids Breaks down cells when it’s time for them to die Removes waste from cells http://library.thinkquest.org/12413/structures.html

22. Vacuoles Vacuoles are storage sacs wastes and water. http://library.thinkquest.org/12413/structures.html

23. Cytoskeleton Cytoskeletons are thin tubes/filaments –Give shape/support to cell from inside –(Like tent poles hold up a tent)
