1. Cell Structure & Function http://koning.ecsu.ctstateu.edu/cell/cell.html

2. Structure What cells are made of and how the cell is out together.

3. Function The processes that enable a cell to stay alive and reproduce. The jobs of the organelles inside of a cell.

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

5. The discovery of cells In 1663 Robert Hooke used a microscope to look at the structure of a piece of cork. Cork is the bark of the cork oak tree, made of tiny cells that are no longer alive. To Hooke, the empty spaces in the cork looked like tiny rectangular rooms.

6. 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.

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

8. Two Types of Cells Prokaryotic Eukaryotic

9. Prokaryotic One-celled organisms, Bacteria Do not have a nucleus http://library.thinkquest.org/C004535/prokaryotic_cells.html

10. Eukaryotic Contain organelles (little organs) Most living organisms Have a nucleus PlantAnimal http://library.thinkquest.org/C004535/eukaryotic_cells.html

11. “Typical” Animal Cell http://web.jjay.cuny.edu /~ acarpi/NSC/images/cell.gif

12. http://waynesword.palomar.edu/images/plant3.gif “Typical” Plant Cell

13. Cell Parts Organelles

14. Surrounding the Cell

15. Cell Membrane Surrounds and protects the cell’s contents like a fence or a wall. Outer membrane of cell that controls movement in and out of the cell – gate keeper Keeps harmful things from going into the cell. Lets waste material out of the cell. http://library.thinkquest.org/12413/structures.html

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

17. Inside the Cell

18. Nucleus Directs cell activities Brain of the cell Contains genetic material - DNA

19. Chromosomes In nucleus Made of DNA Contain instructions for traits & characteristics http://library.thinkquest.org/12413/structures.html

20. Cytoplasm Gel-like mixture that protects the organelles Cushions the organelles

21. Endoplasmic Reticulum Moves materials such as protein around in cell Transportation System http://library.thinkquest.org/12413/structures.html

22. Ribosomes Each cell contains thousands Make proteins Proteins are needed for healthy cells http://library.thinkquest.org/12413/structures.html

23. Mitochondria Produces energy through chemical reactions – breaking down fats & carbohydrates “Powerhouse” of the cell http://library.thinkquest.org/12413/structures.html

24. Golgi Bodies Protein 'packaging plant' Packages the proteins to be moves through the cell by the endoplasmic reticulum http://library.thinkquest.org/12413/structures.html

25. Lysosome Digestive 'plant' for proteins, fats, and carbohydrates Transports undigested material to cell membrane for removal Digestive system for the cell http://library.thinkquest.org/12413/structures.html

26. Vacuoles Membrane-bound sacs for storage, digestion, and waste removal http://library.thinkquest.org/12413/structures.html

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

30. Questions What two parts would you find in a plant cell that you would not find in an animal cell? What is the digestive system in a cell? Which organelle is used for storage? Why don’t animal cells have a cell wall? Which organelle acts as the transportation in a cell? Which organelle makes protein? Which organelle packages protein to be moved throughout the cell?

31. How do cells reproduce? Which part of the cell can be compared to as a gatekeeper? Which type of cells do you have – prokaryotic or eukaryotic? What is the job of the cytoplasm? Where is your genetic material (DNA) located?

32. How things move in and out of a cell Active Transport Brain Pop Passive Transport Brain Pop
