1. Cell Structure & Function

2. 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.

3. Definition of Cell A cell is the smallest unit that is capable of performing life functions.

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

5. Two Types of Cells Prokaryotic Eukaryotic

6. Prokaryotic Do not have a nucleus http://library.thinkquest.org/C004535/prokaryotic_cells.html

7. Eukaryotic Have a nucleus (DNA contained in nucleus) More complex that prokaryotes PlantAnimal http://library.thinkquest.org/C004535/eukaryotic_cells.html

10. Cell Parts Organelles

11. Surrounding the Cell

12. Cell Membrane Outer membrane of cell that controls movement in and out of the cell Double layer Found in animal cells http://library.thinkquest.org/12413/structures.html

13. Cell Wall Most commonly found in plant cells & bacteria Supports & protects cells http://library.thinkquest.org/12413/structures.html

14. Inside the Cell

15. Nucleus Directs cell activities (Capital) Contains genetic material – DNA (so it can reproduce). This is contained in things known as Chromosomes

16. Cytoplasm Gel-like mixture –This is the gelatin-like material where all the organelles are located. Surrounded by cell membrane/cell wall

17. Mitochondria These are the power houses of the cell. (Power Plant) –These are organelles that use oxygen to get energy from processing food. –This organelle provides the cell with the energy it needs to do its job http://library.thinkquest.org/12413/structures.html

18. Ribosomes Each cell contains thousands. (Construction Workers) Make proteins (which is what the cell is made up of) –Found on Endoplasmic Reticulum & floating throughout the cell http://library.thinkquest.org/12413/structures.html

19. Transport Systems in Cell

20. Endoplasmic Reticulum Moves materials around in cell. (Highway) Smooth type: lacks ribosomes Rough type (pictured): ribosomes embedded in surface http://library.thinkquest.org/12413/structures.html

21. Golgi Bodies Protein 'packaging plant‘ Alters proteins into usable forms for the cell. (Post Office) Also moves materials within the cell Also moves materials out of the cell http://library.thinkquest.org/12413/structures.html

22. Lysosome Breaks down and transports undigested material to cell membrane for removal. (Trash Removal) http://library.thinkquest.org/12413/structures.html

23. Vacuoles Membrane-bound sacs for storage, digestion, and waste removal. (Storage) Contains water solution http://library.thinkquest.org/12413/structures.html

24. Plant Cells Only

25. Central Vacuole Is a large Vacuole in the middle of the cell. Plants do not typically have more than one vacuole. Help plants maintain shape http://library.thinkquest.org/12413/structures.html

26. Central Vacuole Is a large Vacuole in the middle of the cell. Plants do not typically have more than one vacuole. Help plants maintain shape http://library.thinkquest.org/12413/structures.html

27. Chloroplast Usually found in plant cells Contains green chlorophyll Where photosynthesis takes place http://library.thinkquest.org/12413/structures.html
